Via Yahoo News, Reuters reports families of children shot at Sandy Hook elementary school in Newtown, CT, are suing gun manufacturer Bushmaster for building the AR-15 assault rifle used in the killings. Should they win we will have put our foot on a slippery slope.
There are several lawful uses for the weapon in question. There are also lawful uses for a Chevrolet. Suppose a bad person uses a Chevy to run down and kill a crowd of people, is it General Motors' or the dealer's fault? Suppose someone evil takes a pillow and uses it to suffocate their old granny, is that the fault of the pillow maker and/or vendor?
Knives, baseball bats, fireplace pokers, archery equipment, even a length of clothesline rope can all be lethal weapons. Ditto a broken bottle or a hammer. Should all those manufacturers be held liable for murders done with their products? I don't think so, I'll bet you don't either.
