Sweden is facing a crime wave of rape, gang bombings, and assassination, with mass immigration being blamed for the rise in criminality. The country, once known for its low crime rate, is now experiencing rampant murder, gun warfare, a drugs crisis, illegal prostitution rackets, and a rape epidemic. The rise in criminality is attributed to gangs comprised of first and second-generation migrants. Bomb explosions have become an almost everyday occurrence, and Stockholm's per-capita murder rate is now roughly 30 times that of London. The Swedish government has tightened citizenship rules and is offering grants for migrants to return home.
