What people forget is, yes, its a lot of police in DC. But, most of the police agencies outside of MPD is federal agencies with their own missions. Capitol Police, US park police, Secret Service UD, FBI Police, and etc. sure, they can assist MPD, but leadership in those agencies limit the amount of police work they can do. Most of their sole focus is protection of those buildings and the surrounding areas near the building, or what they call, MOU. MPD is the main police agency in DC. US park police have jurisdiction all over DC, but it’s not that Many of them that’s actually patrolling because of how much less police officers they have.
I say all this to say, MPD has to pretty much handle everything with the low manpower and insane police reform, so their hands are brutally tied.
