I'm my opinion any normal person should not be allowed to have a gun at all, rather it should only be for any government or states person, police, army, etc.
I say this because there are so many shootings happening and I think that most people who want it to be easier to buy guns, are the bigger threats.
For regular people there criminal records should be checked if they want to buy a gun and also check what they do for a living to better understand the reliability of that person.
