Not only a Congress member, but also a Federal Judge along with several other people. It happened at a town hall sort of "meet your Congressman" event, located a grocery store. One 9-month old child was killed.
It is rumored that the shooter is 22 year-old Jared Loughner. Looking at some of his YouTube videos, those he made and those he "likes", it's quite clear this guy is psychotic.
Burning American flag. How patriotic.
Very sad day. Now get ready for more crackdowns on the general public.
