"The fact the the shooter was wearing body has been on my mind."
I had a very good instructor in ccw class who worked very hard to keep up to date on all the laws and media coverage as well. The media reported the kid as wearing full body armor before anyone had the chance to determine this for sure. By the time the report by the police came back the mistake had already been made. He was wearing a "tactical vest" not body armor. not one ounce from the information given to me. This does not mean one may not try that in the future, im almost certain some coward will. I believe t33 tokarev rounds and buffalo bore 180gr hardcast .357magnum can defeat most vests obtainable to civilians within reason.
