Port Arthur Massacre. Refuse to believe that a man with an IQ of 66 could have done it considering the kill/wounded ratio, the number of "head shots" and the fact he was left-handed firing a right-handed weapon lead to so many deaths.

The man had to take his firearm to a gunsmith to clear the action of one of his firearms because he couldn't. Doesn't sound like a skilled, efficient killer to me.

It was done to disarm a nation, and not by Martin Bryant.

Even if was full retard, he could not have been that effective.
