I agree, having listened to just one call. It was an old lady who had lost her glasses, and was clearly in a state of genuine distress and confusion. Of course, it wasn't something the police could deal with, but she was certainly not a prank caller. I see no reason why her mental infirmity should be paraded by the police on youtube.

Anyone who feels the same way might want to complain by sending a message to Avon and Somerset Police on youtube here
