Clearly unstable bad guy steals a truck then leads a city police car on a chase.  Bad guy then pulls over, reverses and rams police officer and vehicle, takes off again.  Bad guy then encounters Sheriff officer, rams his car bursting it into flames – takes off again.  Bad guy encounters third officer, pulls over and attacks officer while trying to take his gun.  Officer shoots and wounds bad guy.
I doubt you could find a better representative video showing how various law enforcement agencies are fearful of doing their job amid the current anti-police climate.  In this video the County Sheriff is almost apologetic for law enforcement having to do their job.
