I wholeheartedly agree with someone's right to protect themselves, I wouldn't be a police officer if I didn't think so. I just feel that in the UK and Greece hand-guns are not a necessity to do it.
In the US off course I think it would CRIMINAL to pass ANY law that prohibited a citizen to have at least 1 fire-arm in his own home. With all those guns around, i would not feel safe without one myself.
