Repeal the Lautenberg Amendment.
For those that think "red flag laws" would be "sensible gun control", the Lautenberg Amendment should be a case study of how they will be used. I can't tell you how many careers I've seen ruined by accusations that were either unsubstantiated, false, or not at all violent. All without due legal process. Now consider that all conservatives are slowly being lumped into categories that are considered undesirable or illegal.
