This has what to do with Trump supporters?

There is no correlation between political opinion and what happened. Any correlation is simply generated by your own opinions to stir up falsehoods. This was a personal decision by this officer's supervisor. I am sure the supervisor wasn't staring at a Trump poster saying MAGA instead of YOLO right before they made the call to arrest the nurse.

I'd gamble to say most Trump supporters likely support the nurse for common sense reasons.
