Are you high ? <| sep |> You can ' t just buy a gun and carry it . You need to get a permit to do so . And what more do you want than a background check ? Felons can ' t buy guns . People that have attempted suicide can ' t buy guns . People that have ever been diagnosed with mental health issues cannot buy a gun . People that have ever been convicted of domestic violence cannot buy guns usually this one is for a set time limit from one year to many years . There are many people who cannot buy guns . If you can pass a background check why shouldn ' t you be able to buy a gun ? And to add take Omar Mateen for example . He was one of our lovely examples of exactly who shouldn ' t , but did anyway . Under investigation by the FBI , TWICE . People were appalled that a person like that could buy a gun . Then again , Hillary Clinton was under investigation by the FBI many times . She was allowed to run for President . Do there need to be some changes ? Sure . Should we just not let people buy guns ? No , don ' t be stupid .
