When I was in Warsaw I got fined by police twice in one day. Once for jay walking and the second time for- I kid you not- not having a ticket for my bag on the bus. I didn't know either of these were a crime, I now suspect the jay walking was a genuine crime, as I've since heard of it being a thing in other Eastern European countries, and the bag thing may have just been made up so they could make money.Warsaw. I was in Krakow for a day so can't really comment about them
The Russian police are pretty bad, especially in terms of trying to get bribes off you. To be fair the Ukranian lot were alright when we played Shakhtar Donetsk. At football the Italian and Spanish OB are pretty bad.
