One odd factor is to this day, no one has said what type of gun was used in the shooting.
Added to this...an FBI vehicle was broken into a an hour or two prior to the shooting, and a 40-cal Glock was taken. It was about a 20-min drive from where Rich was shot.
I always thought that story was suspicious. Was a female agent I believe. I am quite sure protocol should have prevented that!
This only says small caliber.
