"You will go to jail forever" and "You will be completely unemployable forever" are still two surprisingly effective deterrents against the vast majority of the population when they have a job.

There's lots of stuff you "could" do everyday, but the probability of getting caught is high, the ultimate impact to anyone else is low, and the severity of punishment immense.

All that changes quite significantly when even basic access control is lost and the building is overrun by unidentified belligerents for a few hours. I'm betting a number of foreign intelligence agencies were scrambling to see if they could take advantage usefully.
