From FB friend:
So, as I was about to park, I saw this vehicle, so I quickly got out of my car and took a picture as it drove by. As the driver saw me do this, he slammed on the brakes, and asked, "Do you have a problem?" To which I replied, "Just taking a picture. Is that illegal now?" He then eeked forward a few feet and stayed there in the middle if the road for about a minute and a half until a car approached him from behind, forcing him to move... This, ladies and gentlemen, is a FEDERAL POLICE FORCE. Here. In Grand Junction. Feel safe yet?
I found this:
On October 28, 2009, U.S. President Barack Obama, signed legislation which effectively transferred the Federal Protective Service from the U.S. Immigration and Customs Enforcement to the National Protection and Programs Directorate of the Department of Homeland Security.
