Ok, so as I understand it, the guy got pulled over for a broken tail light (classic dick cop move), resisted arrest, got tased, ran away, the cop plugged him 8 times in the back, the guy died, and cop was arrested for murder.
Lessons Learned:
1. If you're not a cop, don't resist arrest or run away from the po-lice.
2. If you are a cop, don't shoot an unarmed suspect in the back, or else you're going to be charged with and likely convicted of murder.
Sounds like the cop is going to get exactly the consequence he deserves. Am I missing anything else?
