There was a self defense situation in the Detroit metro area. The incident went like this:
A white, pregnant woman allegedly bumped into a black teenager. The teenager went and got her mother, who approached the white woman and demanded that she apologize. Things escalated into a verbal argument, and that is where the video, being recorded by the black teen, begin:
Note that the couple attempted to pull away and the black mother stepped behind the car to block their egress. After being unable to leave, the white couple drew a firearm.
The white couple has been arrested and charged with felonious assault and, if convicted, face up to 4 years in prison.
This again reinforces my opinion that you need to have a dash cam AND if anyone attempts to stop you from leaving by throwing themselves in front of your vehicle, do not get out. Just floor it and leave.
