If you were there with a gun, you wouldn't have the first clue about what to do. Talking big online about killing people is probably the most cowardly act I can think of, next to the disaster that took place yesterday.
Besides, you're jumping to conclusions from second or third hand accounts of some news, which nobody knows for certain is true.
