The ones that I met included a scary looking one with a beard

We had a stall just inside the door where they were set up so I spent quite some time knocking around them. At one point, someone with an attitude went to beardy one and told him to stop wasting his time and get out and catch some criminals

I was amazed how polite the bobby was...
