Guns vs crime, or keeps guns from everyone?

Here is the thought, if a person was able to have a gun at his/her hip or concealed in their purse or pocket would not lessen crime? If some thug thinking to make a victim of someone would not know how much resistance they would get. They might think twice that the wallet they want to take might not be easy, or if the person is armed or if they are a better shot than they are. Not to mention someone trying to enter your house or jack your vehicle, they would have no ideal if they would get fired on. That element of the unknown might thwart some thugs from even getting started.

Would you believe it would be like the wild, wild, west? People will would shoot at other people because they got cut off on the freeway, seen a guy chatting their sweetheart of some trifling thing like that?

Which would it be more, hot head blasting away or responsible people protecting their property and families?
