In the coming days, we will hear a familiar profile about the Broward County school shooter. (No, I will not name him, for the reason below.) He was mentally deficient. He was a loner. He expressed violent tendencies. And likely, if the pattern holds, he was prescribed some kind of drugs to control his behavior.
But there is also a media behavioral profile for these situations, and it is perfectly matched to the desires of a deranged person who would like to go out in a blaze of glory.
