“Everything else is rampant do-gooderism, Nanny State crap, or outright Police State tactics.”
I agree; Constitutional issues aside, this kind of thing used to be resolved by asking the twerp to “step outside.”
Everyone makes a police issue of things now.
Our Declaration of Independence put forth a Natural Rights philosophy which was put into practice in our Constitution.
There is no Natural Right to deceive, and thus no Constitutional right to impersonate a decorated veteran. What you or I consider to be bad law is not necessarily unconstitutional.
