Typical liberal response would be that we need a law.
I don't need any law to do what is lawful.
If da po po gots a problem with it, then it's just that... their problem.
If the gen public thinks it's illegal, then that's their problem.
In either case, ignorance of the law is no excuse.
I don't think we even need a CPL! Works in other states.
I don't think we need to register pistols either.
But the pansy liberal minded will say there is a need for regulation of some sort.
