All he had to go off was a vehicle with 2 teenagers inside and the call from his girlfriend that there were trespassers on the property. Depending on what exactly was said on the call and what happened between him blocking the vehicle in and the shot, he might just have shit trigger discipline and his girlfriend is the one who is super scared of anyone she sees on their security cameras. He is still an idiot for trying to block their vehicle in any case though.
