Oh yeah, the cops are forced to chase. Courts have said cops don't have to protect you. Have they said that a cop must pursue a fleeing suspect? It seems to me more like something the police want to do (drive fast and take down the motherfuckers not respecting authoritah!) rather than something they have to do. Hard to imagine the courts saying cops have to put everyone on the road's lives in danger with their speeding (and of course "making" the fleeing suspect drive recklessly due to being pursued).
Not gonna like you just described the role of Highway Patrol pretty well. So I would say yes. That is their job.
