Sure you can have this "discussion" but it comes off as needless (and probably racist) concern trolling. The Sweden thing is a favorite among reactionaries trying to mask their racism. The homicide rate in Sweden is lower than Canada. It's lower than Finland.
Indeed Sweden as a whole is safe, but organized crime related gun violence has become a problem of different size than here in Finland for example. It's quite worrying as gunfights between gangs do carry a high risk to other people who just happen to be nearby. A typical stabbing at least here in Finland involves drunks or drug addicts and happens in a private apartment.
On page 12 you can see statistic of gun-violence related deaths per million inhabitants in Nordic countries. Sweden is clearly doing worse than other countries, where overall trend has been declining rather than rising. The higher rates in Finland at the beginning are due to statistics also including stabbings.
