Nope. That’s a misdemeanor.
Nope. Felony murder is predicated on a short list of other crimes, and unlawful entry or rioting are not among them. Murder and kidnapping do qualify, but you have to prove that the person either did the murder (of the cop), or intended to murder or kidnap someone within the capitol.
THOSE are not federal charges, murder can be a city of DC ‘charge’ and every one of these people should have a fun visit to CITY lock-up in DC for the duration of their court cases.
Felonies in DC are effectively federal charges, and are prosecuted by the feds. Where they get locked up doesn’t matter much, but they can be pardoned by the president.
