Mustard,
It's already been mentioned that in the U. S, the horse has already bolted, guns are everywhere and are easy to get. Does it make America safer? Tough question to answer. It doesn't stop crime. Does it even deter crime?
If a crim has the intention of armed assault or robbery, he already has the advantage because he initialises the crime. He has a gun ready, loaded and has intent. Unless the victim happens to have a loaded weapon within reach at the time of the crime, the crime will be committed. Any self defence instructor will tell you that if someone pulls out a gun and asks for something, the best option is usually to give them what they want. If someone is going to shoot you, they are going to shoot you.
Nothing gives me more satisfaction than seeing victims fight back and watching the tables turned on criminals while attempting to commit a crime and it sometimes happens but is it the exception or the rule?
Some of the arguments for open access to guns seem delusional.
