I may have implied own/lease, which isn't exactly true, but it still boils down to jurisdiction. As I've said before the FBI has a uniformed division that is only responsible for the Hoover building to the sidewalk around it. From the sidewalk to the street is Metro DC and the next block is Capitol Police. As you said it can also be what's inside in addition to other things (owned/leased or shared between local/fed) that determine who's responsible.
Jurisdiction. Responsibility.
It reminds me of folks standing in their yard, filming LE out on the street in front of the house..
It makes me wonder who's "jurisdiction" it is to kick folks door in, whip/shoot their ass, take their guns and take that whipped/shot ass to jail, without "responsibility" for having to justify it in light of the Constitution, (State or Federal)...
Since anybody with government issued kit is happy to do it, I'm guessing that's a question of overlapping jurisdiction, huh..
I'm sure that no LE Agency instructs Agents or Officers to employ "intimidation" tactics to gain "compliance" in a "free, Constitutional Republic". There's no need to employ such tactics on citizens that haven't even been formally accused of a crime, (therefore innocent, by definition).
It's a free country, after all...
