That is probably true. My experience is the police departments are very segregated in DC. Park police cover things like Layfette Park across from the WH but that DC police have no jurisdiction there. Park police may Jace had jurisdiction on the outside grounds but Capitol Police likely had jurisdiction over the actual building.
“Park police may have had jurisdiction on the outside grounds but Capitol Police likely had jurisdiction over the actual building.”
That sounds correct.
The Park Police were witnesses to what happened on J6 and they could have stood up and defended the J6 political prisoners but they were intimidated by the fascists who control DC.
