No, I wouldn't either, but she didn't act like she thought he was a going to a be a problem. She calls an adult male (and he was not weak looking) into her office, with only her young (teenage?) son there as well, to slap the cuffs on him? Aside from the young boy probably not being of much help in an altercation, it was her son for crying out loud. Who puts their kid in that situation?
In any case I don't see from the video how she was not convicted.
the charge was 1st degree murder. it wasnt pre-meditated so she got off.... now manslaughter or 3rd degree murder, she'd be rotting behind bars
