I think when I see a policeman looking at me he will think I look guilty and must have done something wrong, so then I try not to look guilty... And end up looking guilty.

The other thing is I have seen them acting really aggressive when there is no need, when they are dealing with ordinary people, not criminals.

However, good and bad, as everywhere. My godson is in the police, and my aunt-in-law's brother was head of the Flying Squad at Scotland Yard. Many years ago...
