If you're not an elite or a politician you better have a way of protecting yourself - they aren't going to protect you. No one needs serious firearms but one needs protection.
I haven't had to protect myself from physical violence since 17 I'm 66 now. Threats of violence are rare for me here in the US. I think this whole gun for protection thing just appeals to people unjustified fears and gives them a measure of false security.
They need to make stricter laws and limits as to how much fire power a person can have, get rid of the mega clips and automatic military type weapons. The right to bare arms was written when all they had was flintlocks and black powder surely this was not what our early father had in mind when they wrote the constitution.
