Like a K-9 unit, discretional use of a police vehicle’s mass is really just a logical extension of an officer’s ability to protect the public by rapidly disabling suspects. Think of the advances to officer safety, and think of the savings to the taxpayer from reduced disability claims by public servants like Trooper Garren. Any conviction in this case sends the message that officers should not seek the most basic physical protections from the criminal element. That, my friends, opens to the door to anarchy.
