For the last time nik, no I don't think you should be able to keep an active nuke in your yard or anywhere, they're far far too dangerous and a national security risk. They're at least 1000 times more dangerous than any assault rifle you care to name (hence the ice cream vs. rat meat comparison), it's like comparing a knife to several tanks.
So there were 680 accidental gun deaths in 2006.
How many people need to die before its a problem that needs correcting? This isn't ice cream.
