Ok, Sander- I got a little time so I will try to post some stuff.
To check the stats- I would advise taking a look at the older threads where this discussion arose. A lot of those stats back there are pretty good and from decent authoritative sources.
You asked- does gun control work or succeed-
A better question is, what kind of gun control? A more important question- how do you measure success.
Take for instance a rule that prevents criminals from buying guns by forcing all legal gun owners to acquire permits. How do you measure its effectiveness? If gun crime increases or even stays the same, does that mean that the gun control didn't work? Perhaps, but also perhaps you have a problem that if the gun control didn't exist you'd have more criminals buying guns and the crime rates would be even higher. You might think of this as the "dogs that don't bark" or how do you prove the nonexistence of something.
This is made more difficult given the nature of crime, especially in the US. I believe in the past we both agreed that guns and crime do not exist in a mono-causal relations. In otherwords, guns alone don't cause crime. Criminal behavior is rather a consequence of social, economic and political circumstantial factors as well as the mental state of individuals. It may be that homicide rates in the US are higher than in Europe because Americans are more prone to kill each other. Maybe. But an alternative explanation is that crime rates are different because circumstances are different in the US and Europe- for instance, Europe has better social safety nets than the US and offer greater opportunities for poor folks to get by. In the US, the collapse of industrial cities led to economic downturns that led to an increase in crime.
This discussion grows more complicated because of the political nature of the gun control debate in the US - which in some cases has affected the nature of studies on this topic (which both BN and I noted above).
Ok- so lets start with some general background-
From the University of Utah med Library-
http://library.med.utah.edu/WebPath/TUTORIAL/GUNS/GUNSTAT.html
More on the relationship between guns and homicide rates can be found here - at the US Department of justice site-
http://www.ojp.usdoj.gov/bjs/homicide/weapons.htm
and more broadly-
http://www.ojp.usdoj.gov/bjs/homicide/homtrnd.htm#contents
Looking at the stats reveals a few interesting things I've argued before-
(1) Homicide rates are especially high in cities and among urban minorities (especially blacks and increasingly among latinos)
(2) Those homicides occuring outside large cities and those populations often involve those that the killer has some level of acquaintaince relationship- frequently family, often spouse. The victims are oftem female.
The Utah data also bears this out.
Ok, but that doesn't get us to gun control data.
Gun control involves a variety of different types of control. These controls vary in the US by the state. Those variations by state and control can be found here-
http://www.stategunlaws.org/
Compare for instance Georgia-
http://www.bradycampaign.org/legislation/state/viewstate.php?st=ga
to New York
http://www.bradycampaign.org/legislation/state/viewstate.php?st=ny
Now folks down South might argue that New York has a higher rate of gun violence than Georgia- Not exactly true. If you compare Atlanta and New York, Atlanta is actually significantly more dangerous than New York.

Or even Richmond Virginia to New York-
http://www.areaconnect.com/crime/compare.htm?c1=new+York&s1=NY&c2=Richmond&s2=VA
Does that mean that crime stats are working? Or are the populations of those states more likely to commit crimes?
Hard to say, but it does reflect a trend- that the relationship between guns and crime differs depending on your locality- whether you live in a city or whether you live in the country.
Interesting- the majority of the public does support more gun control-
http://www.jhsph.edu/gunpolicy/surveys.html
Or- so what about gun controls? A lot of the research on this has been taken from a public health approach. Among those doing the research come from John Hopkin's University-
http://www.jhsph.edu/gunpolicy/faculty_research_pubs_gpevals.html
Ok, but wait a minute- Gun advocates would argue that criminals will still get their guns and legal owners wouldn't have them.
Well, lets think about that. Even states that regulate guns don't generally take guns away from citizens, but it might restrict your ability to carry. Does that work for the criminals too?
Yes-
Afterall, the way criminals still get guns is by importing them from states that have soft gun control rules- As noted
here
But more to the point- Gun Controls even handicap the capacity of criminals to get guns-
Underground markets
Half-cocked

From The Economist print edition
America's illicit gun-market is surprisingly inefficient
Get article background
AS AMERICANS digest the news of another gun atrocity, a mall shooting in Nebraska on December 5th, they cannot be blamed for thinking that guns are in too ready supply. But an article in the latest Economic Journal* suggests that the demand for illegal guns, at least, is not met as easily as people might fear. Sudhir Venkatesh, now of Columbia University, has talked to 132 gang-members, 77 prostitutes, 116 gun-owning youths, 23 gun-dealers and numerous other denizens of Chicago's Grand Boulevard and Washington Park neighbourhoods. He did not find many satisfied customers.
Chicago has unusually tough restrictions on legal handguns. Even so the black market is surprisingly “thin”, attracting relatively few buyers and sellers. The authors reckon that the 48,000 residents of the two neighbourhoods buy perhaps 1,400 guns a year, compared with at least 200,000 cocaine purchases. Underground brokers sell guns for $150-350, a mark-up of perhaps 200% over the legal price. They also demand a fee of $30-50 for orchestrating the deal. Even then, 30-40% of the transactions fall through because the seller cannot secure a gun, gets cold feet or cannot agree on a location for the deal.
Buyers also find it hard to verify the quality of the merchandise. They often know little about the weapons they covet. “Tony”, who owns a .38 calibre handgun, learnt how to use his weapon by fiddling with it. He even put a stone in it. “Did it fire?” Mr Venkatesh asked. “I'm not sure. I think it did,” Tony said.
Fortunately for Tony and his peers, their rivals and the victims of crime cannot tell if their guns work any better than they can. Often, showing the “bulge” is enough to gain the respect of rival gangs. In robberies brandishing the weapon will usually do. Storekeepers do not wait for proof that it works.
Markets can overcome thinness, the paper says; they can also overcome illegality. But they cannot overcome both. A thin market must rely on advertising or a centralised exchange: eBay, for example, has dedicated pages matching sellers of imitation pearl pins or Annette Funicello bears to the few, scattered buyers that can be found. But such solutions are too cumbersome and conspicuous for an underground market. The drugs market, by contrast, slips through the law's fingers because of the natural density of drug transactions. Dealers can always find customers on their doorstep, and buyers can reassure themselves about suppliers through repeated custom. There are no fixed and formal institutions that the police could easily throttle.
Indeed, the authors argue that the gun market may be threadbare partly because the drug market is so plump. Gang-leaders are wary of gun-dealing because the extra police scrutiny that guns attract would jeopardise their earnings from coke and dope. Even Chicago's gang-leaders have to worry about the effect of crime on commerce.
AN inefficient market- driven by gun control laws, is a good thing. Making guns easier to get, by relaxing gun control laws- would allow criminals easier access to guns.
Consequently, criminals buy guns in states with lax laws and ship them to states with harsher laws-

(Oh and the link to alcohol and gun violence-
http://www.foxnews.com/story/0,2933,510475,00.html)
More coming.
To answer your question more directly does gun control work-
yes-
Why- it makes it more difficult for criminals to own guns and consequently handicaps their capacity to do violence to each other.
Do safety locks help prevent children from shooting themselves? Yes
Would registration requirements limit the distribution of guns to criminals through gun fairs? Or do bulk sales restrictions frustrate the dissimination of guns to criminal organizations (or is it a bigger pain in the ass to buy guns in Virginia than New York if you're a New York gang?- answer- yes).
SHould there be consumer safety standards? Or- should people who own guns and their families be required to take a gun safety course - even gun advocates support the notion that people should be trained to use guns safety- something the NRA supports. So does gun manufacturer Ruger (perhaps to limit liability?-
http://www.ruger-firearms.com/Firearms/PDF/Blue Book.pdf)
Honestly, I tend to believe that idea that all guns could be removed from US society is insane. There are just too many guns out there and most of them won't be used to do violence against anyone. Gun advocates often see every restriction as an infringement or threat to their liberties- they shouldn't. That level of gun control would never work. But should we restrict guns or limit the ability of guns to get to criminals- yes. I think most sensible people would agree.
In many states its easier to get a gun license than a driver's license. Safety standards on children's toys are harder than on some guns. (GuncontrolinAmerica. By: Singh, Robert. Political Quarterly, Jul-Sep98, Vol. 69 Issue 3, p288, 9p)
Is gun control the answer to all gun related crime in America? All homicide? Absolutely not. Can Gun Control reduce crime and gun violence- yes. But gun control doesn't exist in a vacuum nor can gun control be seen as the answer to all these problems. Furthermore, the gun control advocates have to acknowledge the danger of going "too far" in trying to end gun violence.
But hey, that's all part of the debate.

Effects of restrictive licensing of handguns on homicide and suicide in the District of Columbia
C Loftin, D McDowall, B Wiersema, and TJ Cottey
Abstract
BACKGROUND. Whether restricting access to handguns will reduce firearm-related homicides and suicides is currently a matter of intense debate. In 1976 the District of Columbia adopted a law that banned the purchase, sale, transfer, or possession of handguns by civilians. We evaluated the effect of implementing this law on the frequency of homicides and suicides.
METHODS. Homicides and suicides committed from 1968 through 1987 were classified according to place of occurrence (within the District of Columbia or in adjacent metropolitan areas where the law did not apply), cause (homicide or suicide), mechanism of death (firearms or other means), and time of occurrence (before or after the implementation of the law). The number of suicides and homicides was calculated for each month during the study period, and differences between the mean monthly totals before and after the law went into effect were estimated.
RESULTS. In Washington, D.C., the adoption of the gun-licensing law coincided with an abrupt decline in homicides by firearms (a reduction of 3.3 per month, or 25 percent) and suicides by firearms (reduction, 0.6 per month, or 23 percent). No similar reductions were observed in the number of homicides or suicides committed by other means, nor were there similar reductions in the adjacent metropolitan areas in Maryland and Virginia. There were also no increases in homicides or suicides by other methods, as would be expected if equally lethal means were substituted for handguns.
CONCLUSIONS. Restrictive licensing of handguns was associated with a prompt decline in homicides and suicides by firearms in the District of Columbia. No such decline was observed for homicides or suicides in which guns were not used, and no decline was seen in adjacent metropolitan areas where restrictive licensing did not apply. Our data suggest that restrictions on access to guns in the District of Columbia prevented an average of 47 deaths each year after the law was implemented.

Gun Ownership as a Risk Factor for Homicide in the Home
Arthur L. Kellermann, Frederick P. Rivara, Norman B. Rushforth, Joyce G. Banton, Donald T. Reay, Jerry T. Francisco, Ana B. Locci, Janice Prodzinski, Bela B. Hackman, and Grant Somes
ABSTRACT
Background It is unknown whether keeping a firearm in the home confers protection against crime or, instead, increases the risk of violent crime in the home. To study risk factors for homicide in the home, we identified homicides occurring in the homes of victims in three metropolitan counties.
Methods After each homicide, we obtained data from the police or medical examiner and interviewed a proxy for the victim. The proxies' answers were compared with those of control subjects who were matched to the victims according to neighborhood, sex, race, and age range. Crude and adjusted odds ratios were calculated with matched-pairs methods.
Results During the study period, 1860 homicides occurred in the three counties, 444 of them (23.9 percent) in the home of the victim. After excluding 24 cases for various reasons, we interviewed proxy respondents for 93 percent of the victims. Controls were identified for 99 percent of these, yielding 388 matched pairs. As compared with the controls, the victims more often lived alone or rented their residence. Also, case households more commonly contained an illicit-drug user, a person with prior arrests, or someone who had been hit or hurt in a fight in the home. After controlling for these characteristics, we found that keeping a gun in the home was strongly and independently associated with an increased risk of homicide (adjusted odds ratio, 2.7; 95 percent confidence interval, 1.6 to 4.4). Virtually all of this risk involved homicide by a family member or intimate acquaintance.
Conclusions The use of illicit drugs and a history of physical fights in the home are important risk factors for homicide in the home. Rather than confer protection, guns kept in the home are associated with an increase in the risk of homicide by a family member or intimate acquaintance.
Oh but wait- that's only in bad neighborhoods right?
Nope-

Really- safety locks are a bad thing?
Oh and school violence and homicide- truth is that most kids who die by guns don't die at school but outside of schools. In most of these cases poverty and guns has a higher correlation to the child's death.
