Not really, it has a lower level of crime that the US. I feel much saver than I do in some parts of Canada. No open air drug use and the like. Firearm ownership (legal and illegal) is very high but there is not that much violent crime. I think this is the first mass shooting in a school. The purpetrator came from an affluent family and this happened in one of the wealthier parts of the capital. He used his father's legally owned pistols.
I am slightly acquainted with a catholic of some variety from Bosnia which I've heard is predominately Moslem. He immigrated to the USA and married into a family that owned some ghetto convenience stores in Shreveport. After he shot one of his "customers" and took a gun away from another and gave him a beating with it he seems to have convinced the rest of the clientele to behave. I know Bosnia isn't Serbia but it's the same neighborhood. He goes back there sometimes and tells us there are warning signs at the golf course about places to avoid because of unexploded mines.
