Honestly, I don't want to be on the radar of any entity that is deploying this type of gear in the DC metro area.

I am under no illusion that I can protect myself if targeted by a state based actor. Better to be lost in the crowd.

Best case scenario is it's a legitimate LEO operation.

Worse, it's a federal national security operation.

Worse still, it's a criminal, or foreign national security operation.

Only in the first scenario would the FCC even remotely have the chance to do anything. Even then it might be a legitimate operation, and they do nothing.
