Unironically, cows are great indicators of what’s normal in fields and pastures. They’re up over there investigating ICE because they’ve never seen them or their vehicles before.
During WWII there are stories of both sides having issues in rural France because milk cows would come up to their hiding spots, crying to be milked (going unmilked is painful for dairy cows).
Border patrol is hardly related to our current problems. Even following orders to go stand in a certain place isn't terrible until you actually do something wrong.
The fact that people (National Guard, Marines, whatever) showed up in LA is a problem. Most of those actual people themselves are not the problem.
