Do this sort of stuff day in day out..but that is totally out of order never should there be males present during a strip search and unless they are a massive danger to themselves are they left naked.
A risk assessment takes place whenever anyone is detained in custody, if there s potential for self harm/suicide then clothing is removed and sometimes by force. Get the usual pissed up fool who thinks he is invincible claiming he's going to do this and that and that does lead to a confrontation where they are left cuffed as they are stripped but its always conducted by same sex officers
We do not get the whole picture from that clip i.e the actual booking into custody..but that is fecked up
