What if when you're walking through a store and someone is being slow in front of you, does that make it ok to club them in the head with a bat? This is attempted manslaughter and I am amazed that people all over facebook, and now here, are even remotely siding with the truck driver.
What worries me even more is this happened recently and only ~45 minutes away. I wouldn't do what the Z driver was doing but to think that people freely drive around willing to smash another car simply because it was in the way is unnerving.
