Actually, it's the opposite. Australia is a perfect example. They took away ALL guns from law abiding citizens, and violent crime went through the roof. The criminals STILL had their guns. You think a "gun law" will make criminals say "Oh MY! They have stricter gun laws. I'm gonna go RIGHT now and turn in my gun." Nope.....it won't happen.
If, as in your posting, you say "If somebody is trying to commit a crime against you and you pull out a gun, yeah they might back off and it might save you, but it is much more likely that if they have a gun also that you will get shot and more violence will occur." All that gun needs to do is save my life, or my loved one's life ONCE, and i'd say it was worth it, don't you agree?
Here's the kicker........the bad guy ALREADY has his gun! You think you being unarmed is going to cause HIM to not be armed? Most of these punks are cowards, and will run if confronted with resistence, with a gun in THEIR face. They get their "courage" with their weapon. What would have happened at the Columbine massacre if one or two of the teachers in the school had been legally armed? MAYBE they could have stopped those punks BEFORE innocent children and adults were wounded or killed. Trust me........i DON'T want to shoot anyone, and i hope i never have to. But if someone breaks into MY home and threatens MY loved ones, THEY will be sorry they did. I have owned guns since i was 16. I have YET to commit a crime with one. And neither has ANY of the "gun toting" people in my family. Why do you think Police carry guns? They HOPE they never need them, but if they DO, they want to have instant access to one, for self defense, or the defense of innocent people. Again......the laws affect ONLY law abiding citizens, NOT the punks!
There are right to carry laws all around this country, and it HAS lowered violent crimes where good people were allowed to defend themselves. And where these laws were passed, people had to be trained to properly know HOW to use a gun, so it wasn't just handing people guns to go off shooting like in the old west. Unlike the scum that buys a black market gun for $50 and thinks that makes him a man. And the bad guys will ALWAYS have weapons.
If someone uses a baseball bat to rob a store, and beat the store clerk, should we outlaw baseball bats because SOMEONE might miss use them? Of course not. Or should we outlaw law abiding citizens from driving cars, because drunks kill thousands of innocent people every year using their cars after they get drunk? Again, of course not. So why should law abiding citizens be punished for the actions of criminals? Go after the BAD guys, and punish THEM. Not me!
