I believe guns are the same way.
Whether it be drugs, guns, knives, etc... it all comes down to the person who is in posession of these items on whether or not it will be used for bad things and not just a product of the items being available to everyone. Getting rid of them will not solve the big time issues because if those with bad motive want them, they will get them.
There are also a lot more good eggs out there then there are bad eggs and those good ones should have the right to protect themselves. Banning them would leave the invaded home owner with no option but a kitchen knife while that intruder recieved a gun through the many black market avenues out there available to them.
iPhone = Great gaming device. Don't agree? Who cares, because you're wrong.
