The guy had been to previous meetings and had gotten out of hand in the past. It looks like he was on a suicide mission and wanted the "suicide by cop" after taking down a bunch of folks he didn't like. He managed to kill to police officers. They must have been caught off guard. With incidents like this, I'm surprised that the lawmakers have yet to figure out that "gun free zones" aren't as safe as they're said to be.
Hope people learn from this incident and change the laws.
