No way to prevent this in the only nation it regularly happens. Lol and they put heroic in quotes, like were about to see a bunch of "he was no angel" articles in the coming week.

This is one of the reasons why I hate that one argument about how arming all civilians will prevent mass shootings. Even in in a perfect scenario where some vigilantes all shoot the bad guy, the pigs are going to show up and escalate the situation further, because they're racist, trigger-happy twitchy pigs.
