Should make a couple mentions to that article. The dude had a lever action rifle and those aren't exactly fast on the rate of fire or reload (So he's fucking stupid for one). And the ceremonial guards (The guy that got killed) don't carry ammo with their guns which kinda sucks. The guy was also stupidly unlucky. He did his research when to attack, but fucked up where to attack. What I mean is that there were two rooms full of VIPs to the right and left of him and he's like 'Nah I'm gonna go to the fucking library instead'. Last thing: those 30~ shots the police shooting and missing him.
