Everyone is a victim of their own frame of reference. Like a lot of federal agencies what / how things are done in USMS varies considerably by location. In some places a DUSM may work other duties for 5 years or more before working any fugitive warrants. In other places everybody does everything. In my city the DUSMs do 6 month rotations between the Courthouse and full time on the fugitive task force. The deputies at the courthouse here still have lower priority warrants assigned to them but they work them around /outside court hours.
The USMS do get into a lot of shootings, more per capita than any other federal agency I’m aware of. It’s not a coincidence they are among the first federal agencies to get body cameras which had reduced the number of shootings.
It’s also worth noting there are relatively few DUSM. USMS has supplemented them at courthouses with Detention Officers, Blue Jacket contractors etc for years. The majority of LEOs on the various USMS Fugitive task forces are not DUSM, but rather participants from other local, state and federal agencies.
While there are still full time fugitive guys in the Bureau, and the Bureau does assimilate state and local cases (particularly those with international aspects) IME most offices have a single agent as with a full time or collateral fugitive coordinator.
