This is getting ridiculous. The reason why these classification of mass shootings was invented (by US Congress) is quite the opposite of what you suggest, namely to make sure that gang-related violence and "ordinary" shootings are included into the statistics Why? So politicians can point to cities like Chicago and argue that the police needs more powers instead of having to deal with the unpleasant reality of amok runs and domestic terrorism which cannot be prevented very easily and are often cited as an argument for tighter gun control. Of course, you're less likely to get shot in Europe. If you start cherry picking locations, on the other hand, then I guess the US is 100% safe and crime-free, provided you take your mom's basement as reference area.
