I guess in my opinion you can't eradicate an entire sect of people. You have to operate based upon the assumption those types of people exist. You know there are people that will abuse the fact they can freely access firearms to harm others. You also have studies proving there are direct correlations between firearm ownership and homicides. Based on that, you do what you can to minimise the risk to upstanding citizens, which for me would be imposing stricter gun ownership laws. Also why do people need to own guns? We don't have gun ownership here in the UK, and as far as I can tell no one cares about it either..... We just don't understand why people in the US seem to want their guns so much.
