There was a big scandal in the UK when an English tourist visiting Washington DC was arrested and kept in prison for several hours, just because he crossed the street when the red man was showing! LOL!!! I agree with the USA on that - he should not have done it, and he should have apologised and paid the fine when asked.
In Belarus it is probably illegal too, and I would not do anything illegal here because there are policemen and other people in military uniforms all over the place...!
For some reason they have been in my block of flats several times and knocked on all the doors in the building. I have no idea what they want and didn't open.
Yesterday I saw them deal with a drunk man. They were actually very polite, even though he was practically half dead from boozing. They tried to wake him up in a nice way and asked him to try to stay awake so they could get him to hospital. I have seen police be A LOT worse than that to drunk people in many other countries.
