It'd be problems using it, but even a legal gun can get you in jail if you use it the "wrong" way here. That father who shot those bullies eventually had to pay compensation in the court of appeal, and if not most Swedes had been so pissed that the authorities let all that happen, he'd probably gone to jail too. He won't go to the Supreme court, because he's afraid of getting a harder punishment. Fuck the authorities in this country.
