Can I go to a hypnotist and prove I was hypnotised, d, and filmed?

It is so corrupt! I cannot believe the police condone it. Or won't do anything. Can I go to a hypnotist and prove I was hypnotised, d, and filmed? Is there any way to find it if I don't remember it? I can remember where I was when I could have been hypnotised. Are you conscious when hypnotised?
