Gun control is very effective but to be exact you cant stop something in this world if i have a gun and i wannna shoot to anyone else i could do it, so by conclusion gun control wouldnt be that much effective if the citizen of a country wont abide the rules in everyday life, life is simple why protect yourself if you aint got foos? but there are some crazy people whoo are tooo lazy to work and want an easy money so they would just love to grad your bags , this poverty or poor state of life comes within how much effort are we pushing ourselves to become rich if you got no money and you are lazy you buy or find or ask for a gun and tryna rob someone elses money and then the victim would buy a gun for protection and then they gonna shot anyone else that promotes threat to them.
