should this guy be held responsible?

A horrible accident occurred today in Phoenix, AZ. CNN reports that two news helicopters crashed while covering a police chase. Four people, a pilot and a photographer from each news station, were killed in the accident. No one on the ground was killed.
The CNN story quotes a Phoenix official stating that the suspect in the police chase will probably be held responsible for their deaths.
My question is should that guy be held responsible? Sure, I’ll grant, that if he hadn’t led police on a chase, there would have been zero chance of the accident occurring. However, is it his fault that two helicopters covering his actions came into contact with each other? Throw the book at him for everything else, but is this really his fault?
That being questioned, it is still a sad accident. Let’s keep the four and their families in our prayers.
