You need a license to own any kind of potentially lethal firearm here. You have to earn that license, so weapon crimes aren't that common here. In fact, crimes performed with airsoft weapons are REALLY common, because people just seem to NEED to be illegal, but they're forced to do it with toys.
And some politicians are like "AUGH BAN AIRSOFT GUNS" which is sad, because what they don't realize is that very little harm is done when criminals only have the fear factor on their side. If airsoft weapons weren't so easy to find, they'd have to find some other sort of weapon - makes me think of knives and stronger air powered rifles, if not actual real firearms. If we ban the harmless replicas, the criminals would have to find other weapons. Because I think, if one's set on being a criminal and robbing banks and crazy stuff, one would keep doing it even if one suddenly has no fake gun to wave around to get ones cash.
