Google maps. Zoomed out covered by U.S. immigration detention and freedom for immigrants visitation

I don't know how to upload screenshots of this.

I zoomed out in Google maps because I wanted to look at some geography in Europe. The entire U.S. is covered by pins. They are all prisons or detention centers. All of the pins are subtitled U.S. immigration detention and freedom for immigrants visitation center. I've never seen these pins before when zooming out.

Anyone else see this in maps?
