DC's reaction to Palmer

Wait, take note of non-residents' ID in case the legality of their carrying changes? Would carrying as a non-resident be made retro-actively illegal? Or is it rather that they're not currently sure carrying is legal, and they'd decide later on that it wasn't?

What legal basis would they have to compel a non-resident to present ID assuming they were not driving?

What legal basis? Probably none, except this IS the Dof C, of which all might be considered a security zone. But the real basis they have for demanding ID is the usual one - I'm a cop, I have a gun, do what I say or I'll kill you.

It's rarely that explicit, of course, and it almost never goes that far, but that's always at the bottom of things. Cops can come up with all kinds of stuff to ruin at least your morning, if not your whole day, or even most of your bank account. Won't present ID? Arrested for any number of vague offenses (remember mopery? - supposedly "conspiracy to loiter" ) for which the cop will have some plausible story. You'll be under cop control for several hours, your gun will be taken, probably not returned when you're released, and then permanently lost. You have practically no chance of making a legal claim for damages which will result in net cash in your pocket, there's virtually no chance the cop who arrested you will face any real punishment, and all the cops know this.

Wrangler5: Perhaps there now is a stupendous claim to be made: A 1983 lawsuit, since police interference now rises to the level of a constitutional violation(?)

Maye we on the outside should just fence off DC so they on the inside cannot come out.

Forget it. The courts are ignorant of the Constitution. In DC, ONLY Congress may legislate. Every law passed by any body-politic other than Congress is not legitimate or constitutional. Nada. Congress is granted exclusive, not absolute meaning all legislation of Congress must conform to the Constitution and no other governmental body even one formed by Congress, may legislate in the District. It's in Article I, Section 8. AND Congress is never granted any authority to delegate its powers to any other body. Delegata potestes non potest delegari.

So everything is still wrong about DC and the laws.

I think the obvious reason for noting the ID of anyone who is legally carrying at the moment is so that later, when DC throws up some vastly restrictive concealed carry law that does not allow non-residents to carry, then any future interaction (say a traffic stop) with someone having one of those IDs will alert the police to search him and possibly arrest him for weapons.

Just carry concealed. Problem solved. If you need to shoot a bad guy, you now have some protection for carrying. If you don't have to shoot anyone, then no one will even know it is there. Perfect.
