I can't view the video, perhaps it mentions what kind of gun it was. Also if it was appendix carry, would there still be a shell casing in the van?
Regardless of how it actually happened, it's never a good idea to have Mary Jane as a passenger in your vehicle if you have a unintented discharge. Can you imagine what a prosecutor might imply if he had been forced to use that weapon in a self defense situation? (particularly one where there's no video or witnesses?)In the video, Hale is heard telling police officers he shot himself, that the gun discharged when he drove over a bump in the road. Police found an unspent round in the work van Hale was driving.
