Polish police isn't good ... it is true.
I must say that I was under this impression for many years of living here, but recently I had to go to the Police station and be interviewed because of some bureaucratic cock up in the local driving office here in Pulawy, and they wanted to prosecute me for their mistake. (anyway that's a long story)
I was pleasantly surprised on how friendly and helpful they were and soon sorted out my problem and even reprimanded the local driving office for ever bring this to this stage.
Maybe this is an isolated case, but I was very impressed with the way they dealt with everything.
