Here's a little update:
The deathcount is... I'm too lazy to check. Anyway, it's less than have starved in the Third World up to when you've finished reading this.
The investigation indicates that the roof collapsed due to heavy snowfall; 25 tonnes of compressed ice were too much for it to sustain; I, actually, tend to think that the roof collapsed under the weight of sixty-six thousand feral pigeons that wanted to protest against the incarceration of their brethren, Hamas-style.
At any rate, the Prime Minister Marcinkiewicz and the Minister of Justice Ziobro are busy bees, visiting the collapse site and assuring everybody that it will be ascertained whether the managers of the expo are to be tried for negligence. Fortunately, the PM isn't as blunt as a former PM Cimoszewicz, who, after flood has stricken a few years ago, told the farmers "You should have gotten insurance", leading to his party's failure in the next elections. I was kind of expecting a "They should have been wearing hard hats" attitude from the PM, so I'm pleasantly surprised.
On the most popular internet fora, users are criticizing Marcinkiewicz for showing up on the site, saying he's aiming for an increased publicity. Incidentally, I'm sure he'd be accused of soullessness had he not paid the visits.
In a hotel room, the designer of the hall attempted to commit suicide by cutting his wrists and was taken to the hospital. Allegedly, the design was based on a similar Spanish hall, and there is significantly less snowfall in Spain, a factor that ought to have been accounted for.
The death count could have been even greater, had it not been afternoon already and many visitors had left.
