I'm sure more info will come out as the day progresses, but it's seems like nobody knows what happened at this point.
Appears to be a nut-job who couldn't handle a traffic stop. Lots of sympathy for the cop. No way a stupid traffic stop should result in a shooting. No wonder the cops have gotten so "antsy" when they pull a car over.
Same freakin thing happened yesterday in Moore County NC. Man killed a Moore County Deputy then committed suicide. Wtf.
