No, because people already commit heinous crimes I see no reason to rob the law abiding of an effective means of protection against those that would commit said crimes with or without a gun. It's why shootings happen at malls and schools they are "gun free" except for the shooter, they are provided with a target rich environment that will offer little to no meaningfully resistance. As a result they have a monopoly on force until the police arrive and they shoot themselves or are shot.
