Vehicle plows into crowd on Bourbon St., with 14 fatalities

It's odd. But, he was clearly not stable so it's hard to know what he was thinking or if his plans just got delayed. Maybe he had second thoughts or couldn't work up the courage until then? He had to know he was going to die doing this. Maybe it took him time to finally decide to do it.
This is a decent point. It takes a certain mindset to go into a situation knowing that it's a "suicide mission". Maybe that's why a lot of these people that do these things are ex military? They've been trained to put the mission first and foremost. No, or little, fear of dying as long as they complete the mission.
