Having been in her predicament in my misspent youth, I can tell you that handcuffs applied to tightly can cause nerve damage, cut off circulation, which if left on too long cause just the problem she experienced. Usually a bully with a badge thinks this is funny. The cop should be charged with whatever a good lawyer can dream up and sued along with his employer to the max. I forgot, the cop should join the ranks of the unemployed at the first possible moment. Just my 2 cents.
My local library is forming a SWAT to retrieve overdue books. They will be transported in a old Soviet APC, and be armed with Schmeisser Machinenpistolen, and they will have semi-starved Alsations on chain leashes. Uniform? Black Kevlar everything including helmets, jack boots with hobnails. Trick laser sights, stun grenades, RPGs ... in short everything needed to bring the holders of overdue public library materials to immediate justice.
If perchance, they laser, taser, RPG, or stun grenade the wrong house: TS. It will serve as an example to the rest of the community to shape TF UP ... and get those books back on time!
