As a licensed, insured, and trained motorcyclist I believe fully that if you abuse the privilege with willful neglect for others, a LEO can do what needs to be down to STOP the vehicle. Road rash is not something to be taken lightly. If the rider escalated the actions required by the LEO to the point of vehicle contact, well that and any repercussions lay solely on the shoulders of the suspect. The officers who stood by before rendering 1st aid and calling for medics should be reprimanded, for they forgot at that moment that they are NOT Judge/Jury/Executioner. They are here to protect the peace and that only.
