It's about ease of access.
Sure, criminals will always be able to find a way to obtain weapons, but the harder you make it the fewer criminals will have access.
Also, it isn't like the police are entirely incapable of catching someone trying to obtain a weapon.
Maybe so, but I happen to think that a law would only limit the ease of access for regular citizens.
As far as I know, laws have been put in place to make certain drugs illegal, yet nothing is stopping rule-breakers from manipulating the system and having easy access to it.
Illegal activities take place on a daily basis, the only difference is that innocent civilians are rarely affected because they are granted with the option of taking matters into their own hands.
And true, the police is still a pretty effective organization at countering crime, but they can only do so much when a criminal is knocking on people's front doors.
Is the crime level that much lower in the USA, than countries where firearms are harder to obtain?
Are criminals in countries where guns are banned truly less cautious about committing a crime?
If anything, it wouldn't be that hard of an argument to suggest that those kind of thoughts mean that criminals will always aim to be armed in the States, as they never know when they will not need a weapon to fight off their target (should they also have a weapon).
This kind of thinking would increase the chance for a fatality during a crime, now lower it.
Now, I don't necessarily believe that is the case, but neither do I believe having everyone armed serves as that strong of a deterrent for criminals.
I think it depends on the demographics. I agree that the US still has a substantial amount of crime, even with weapons legalized.
Other countries are built on discipline at an early age, so that might explain why their crime rate is so low even with firearms banned.
But since the US gives a large amount of freedom to its citizens, many of them will go out of their way just to obtain illegal items such as drugs/guns (resorting to stuff like the black market).
While deterrence may not work in every case, it acts as a reliable barrier for law-abiding citizens.
