I assumed we meant more in the generalized sense, IE it's Starfleet ships which do border patrol along the Federation's borders in space, muck like the Navy or Coast Guard patrol the ocean borders of a country's waters, or that Starfleet has an obligation to protect the Federation and its citizens in the same way the military of a country does its home nation and citizens. I didn't think we were suggesting Starfleet is Federation ICE or something.In the US, border protection and law enforcement are done by non-military groups. Well, it's supposed to be. There may be some militarization among those that would make Archer faint.
