Debate: Can stricter gun control laws decrease the rate of crimes involving guns?

Yes, because with fewer weapons, you get fewer crimes.

Take a look at the crime rates of countries like the United Kingdom. Their crime rate is very low, compared to ours here in the United States. Just by simply putting stricter laws in place on who can own them, it will greatly reduce the crimes involving guns.

Past Practice

There was an assault weapon(攻击性武器) ban back in 1994 under Bill Clinton. Shootings and crime did not go down for the 10 years when this law was in effect. Criminals do not follow rules. The law only affects those who try to obey the law to arm them to protect themselves.

Wake up, you Americans!

It's hardly surprising that America has one of the highest gun related murder rates of all countries! And of course guns don't kill people, but the more people own guns, the easier it is to get access to one, the higher the chance of people using it to kill somebody is!

In Germany, we have really strict gun laws and only a few people own guns, and obviously we don't need them. There's no reason that a normal citizen would need a gun! Guns are made for one reason only: killing.

More gun control laws, fewer shootings

On the same day as the Sandy Hook tragedy, a man in China entered a primary school with a knife and injured 22 students on December, 14. However, nobody was killed. Compare that to the 26 students and teachers killed at Sandy Hook in Connecticut with a powerful gun. We must learn something from this tragedy.

Gun violence goes up with more gun control

Criminals will take advantage of the situation. They will do whatever they want and take whatever they want and kill whoever gets in their way. They will get guns illegally. Crime rates go up as a result of more gun control, because criminals know you don't have one, and they will kill you as they like. There is no point in banning guns!
