around 11:30am. Wouldn’t let anyone in. I just so happened to be dropping someone off and I noticed that it was surging 2x and said only 2 cars in the lot so I circled back around and joined in the line to enter the lot. The copsmade eveyone leave and held up traffic to hasten egress. Then, my line started moving and I got a ping at 2x as I came around the bend-never entered the lot -which was blocked. Not sure what was up. Cops making surge.
