It is my understanding that explosives where popularized after an influx of hand grenades from Serbia. Until rather recently these have been categorized as dangerous materials rather then weapons so it didn't carry the same risks being caught with them as with handguns. My uneducated guess as to why the violence is that is has become decentralized. We had a fairly long period with stable power structures in the Swedish underground, there where a few biker gangs that had a few rare and violent bouts bouts but they where infrequent. Today we have a large number of loosely organized criminals that act independently, fighting over much smaller turfs. In some sense this might very well be because the old criminal organizations, populated mostly by right leaning criminals, have failed to integrate potential recruits from different ethnic backgrounds.
