Discription of Events: Actually US government plate. I noticed a large black SUV (Suburban tag US government 0055M) illegally parked blocking the double cross walk (two cross walks a few feet apart) at Pentagon Row. Pentagon Row is an upscale dinning and shopping center. My initial concern was the safety of those using the crosswalk. Approaching cars cannot see pedestrians coming in the crosswalk when someone has parked an SUV there. It is very dangerous. So I went to gather information and left. As you may have noticed from the license plate this turned out to be a US Government Vehicle. I thought it was interesting that a government vehicle would be used to visit somewhere such as Pentagon Row. By Pentagon Rows own description "Welcome to a fantastic little pocket of perfect. Eat til your soul's content. Prepare for total retail domination". Yeah, sounds like official government business to me! But if you think that is questionable use of a government vehicle what happened next is even more questionable. I'm in the parking lot across the street when the government employee drives the government SUV 0055M across the street and then drives up close to me as if trying to scare me. He then starts demanding to know what I was doing and if I was taking pictures. I politely say to him "Sir you were parked in a cross walk:". To which he arrogantly replies "So". He keeps trying to berate and intimidate me so I leave the parking lot. That is our tax payer dollars at waste folks.
