It's not completely impossible to own a handgun here, but it's not easy at all. Carry permits are almost never handed out, and you have to follow a ton of rules. Basically, for a handgun you need to be in a club for sports shooting.
Of course, everyone is crying for even stricter laws now, but honestly, it won't do anything. If even the last legal means are gone, there's still a black market, and you can't really get rid of that. This guy was seriously whacked out, full on paranoia about secret agencies spying his thoughts and stealing his movie ideas and lizard people and really everything you could think of. If he hadn't been in a club he'd have gotten a weapon somewhere else. Oh well, it doesn't matter. Stricter laws will come, they will do nothing, more strict laws will come, they will do nothing and so on and so forth. Whatever. I'm not gonna pretend that the german populace would ever rise up against a tyranny, so it's not like there's any point in having a disarmed populace here, but hey, gotta be safe and sure.
