“Which is fine but why send 7 jackboots for a situation”
Maybe they were picking up a bunch of them at once? Two for each van (3 vans) plus a supervisor. Or maybe they were training other Marshals on how to properly do it so violence doesn’t occur when they go after the others.
Do you want the local Sheriff coming after you to do the Fed’s dirty work? (think about possible future Federal laws that might contradict with State law - like Kansas)
My point in mentioning the Sheriff is that an elected official is more likely to serve a warrant in a sane manner.
