What is the youngest you can be for the police to perform a body cavity search on you?
My friend is 10 and the police thought she had illegal stuff on her because she was on her own is a bad part of town so they arrested her and performed a full body cavity search on her. When she struggled they held her to stop her from struggling. She was raped by someone a few years ago and now is extremely afraid of people touching her. she has breathing problems if they do. She told them that. (In oregon.)
This is indeed an unfortunate situation, and if you are very upset, you should contact the police department and seek answers to the approach taken by the police. It is very hard to give you a clear answer as the circumstances and situation are not known regarding your daughter.
Please call the police department, ask to speak to the Chief of Police, and get answers to this issue.
