to contribute a bit:
Czech Republic - the same as Slovakia.
I've had a chat with a guy from Italy, he told me in Italy scanners are prohibited unless owning italian HAM licence and even then it is only legal to monitor HAM frequencies.
Poland - don't know exactly about the law, but it is possible to buy a scanner in Poland and I had no problems using it.
In Sweden...... ..... You are not allowed to disclose what you have heard on frequencies not intended for the public. I.E. no audio streaming allowed.....
