Nobody tried to get into the Range Rover before he attempted to kill. The first time they stop, after the chase begins, someone does try to gain entry into the Range, and succeeds. The Range's doors were unlocked until the end of the chase. If someone had tried to get into the Range before the chase began, they would have succeeded.
The biker's may have been ass holes, but dude in the Range is a pussy, and attempted to kill.
If I get into a fist fight, and I feel like I'm about to get my ass kicked, am I allowed to start blastin' mother fuckers?
None of us were there. Why is anybody taking sides? All parties involved in this situation made huge mistakes, and should be held accountable for their actions.
I'm all about a person's right to bear arms, and defend themselves and their family. Deciding to take someones life because you're a little bitch and panicked is not what I'm all about.
