Getting rid of unconstitutional gun laws would be a big step in the right direction IMO.
In line with that thought, get rid of all the STUPID laws on the books.
IF the JUSTICE system worked properly, and the COURTS/JUDGES allowed the punishment to fit the crime, then we would find less need for all the silly laws.
Most laws are not made with the idea of STOPPING anything. They are made for many reasons, among which are to ensure employment of lawyers, judges and to give the wealthy and powerful ways to get around the law.
GET IT YET? LAWS are made to enable some to be ABOVE THE LAW.
