Rights to bear firearms, gun controls, have they been really helpful?

I mean almost everyone can have a gun of they wanted to illegally or legally. Having a gun is almost as easy as buying at supermarkets. I don't even think that the existing laws about carrying a gun reduces the crime rate in the country. Not all crimes are committed using guns. What I'm trying to say is that whatever law there would be about guns is that there will always be robbers and thieves and rapists and murderers...
