From what I've read, he did have a warrant out and was well aware of it.
But what did he think he would gain from running? Did he honestly think he would get away?
Isn't there some point where you just say, "That's it...you got me"?
Still no excuse for the shooting...but for crying out loud!
I dunno, we can't ask him.
Again, people run for all kinds of reasons. Most because they're scared and stupid.
Especially since he'd already given the police his driver's license.
