here is the problem with your logic here. the dude was breaking that law, lets say the police cut off the chase and then this idiot kills a family of 4 five minutes later, everyone would be blaming the cops for not chasing him and getting him. also they would be sending out a message saying all you gotta due is speed to get away and we will leave you alone. As soon as the guy did not pull over for the cops he was comitting a feloney (plain and simple), and in the commision of that fellony he got some one killed (plain and simple). is 60 years a bit harsh? yes! did he get some one killed by not pulling over? yes. he took the responsibility of what ever happened after the chase began, he was commiting a crime and he is only lucky the cop got killed. He was weaving in and out of traffic, he needs to own that his actions were fatal.
People make mistakes all the time, and I feel sorry for the guy, but as soon as he decided to run from the cops, he took a step that can not be undone.
as for the "WTF" comment, I assume you are blaming the cops for what this guy forced them to do, It kinda sound like the old question you here after someone has been killed on a motorcycle "Was he/she wearing a helmet?"
