Quoting: FISZ, Post #44
There are professionals that work the train stations. Especially in Warsaw. I'd worry more about pick pockets there than gangsters.
True, however pick pocketers only take your money, gangsters end up killing you.
I have been to poland 10 times and have not been robbed or assaulted (granted I am 184cm tall and 95 kg, fit as a mallee bull) but I must say I picked my mark where I went and what clubs I attended.
Good advice for tourist is to blend in with the locals, ie dress, appearance, and manner, dont't advertise the fact that your from overseas.
When going to a atm machine, observe who is around you, when leaving move in one direction and then double back, observing who is around. may sound strange but it works.
