Organized crime in Sweden likes grenades and some similar explosives, largely because they - by accident - was legal to import a couple years back.

Grenades became much easier to get ahold of than handguns, which have had some weird effects, as they seem to have come to be used as intimidation between rivals.

The use has been dropping the last few years, and should hopefully be back to the pre "legalization" levels soon.

It's all certainly quite unfortunate, but the number of casualties are perplexingly low. It really seems that whomever it is that does these bomb/grenade attacks go out of their way to avoid people getting killed. Not that I understand why exactly, except that it seems to be about intimidation in the majority of cases.
