I used to be a student in Lund.
Yes, lots of harsh people in Malmoe, ha-ha. Once I`ve almost seen a car pursuit, which enden with a tragedy not far from my place.

(I was walking nearby 5 minutes later, seeing lots of shocked pedestrians.)
Lund is just in 10 minutes by train, but is much more "european", polite, bright...
I didn`t feel that it was more dangerous than Russia, though. You can also compare crime rates using numbeo - the percentage of them is 3-4 times higher here in SPb than on Stockholm\Sweden (per 100 000).
