I saw my first one around two weeks ago (my job has me driving between one and two thousand miles/week from No. Ill. to Upper Michigan)...a white Chevy Tahoe with blue lettering and an approx. 3’ wide light bar. The largest of the lettering announced “POLICE” followed by a smaller “FEDERAL PROTECTIVE (or protection) SERVICES” with a smaller DHS (Dept. of Homeland Security) emblem. I have seen three since, two today, always on the interstates. Govt. plates, of course. Maybe they’re here to protect an influx of refugees, maybe not. They have purchased a LOT of ammunition and arms of late. We live in interesting times.
Correction, I didn’t see two today... that was written two days ago to a local board...I copied and pasted in deference to my lazy streak.
I saw one of those driving to Houston the other week.
