Why did the truck driver shoot Selene?

Question

During her escape from the research facility, Selene jumps onto a driving truck.

The truck driver notices her, makes a full stop and she flies over the vehicle. The driver then steps out with a gun in hand, walks up to her lying on the ground and without blinking an eye he shoots her straight in the face.

That was the point were I was completely baffled. What the hell is wrong with this guy?

Maybe he had a bad day, ok. We all know those. But shooting someone cold blooded without even asking why she used his truck as a taxi?

You could argue that he is living in a pretty bad world with vampires and werewolfs and you can never be too careful, but

• There haven't been any werewolf or vampire sightings in years apparently, so he has no good reason to believe she is one of both.
• A normal gun wouldn't help him in this case anyway.

So why is he acting this way? Am I missing something?

Answer 1

I haven't seen the movie, but if it's a semi-truck, or a truck to haul any sort of cargo or materials, he could have thought she was trying to steal something off of his truck. Truckers tend to get pretty touchy about people messing with stuff on their trucks. This character could have just been a bit further on the touchiness scale than usual.
