Sliding tactical police

A tactical police vehicle was speeding down the road. The back of it was round and kind of flattened. There were police in tactical gear hunkered down all around the back. The vehicle turned toward a residential area, then in a calculated, coordinated effort, the vehicle abruptly stopped as the men dove to the ground. They apparently had slick plastic-like pads all over the fronts of their bodies because they all were sliding over sidewalks and through grass toward a specific house. I was standing in their path and had to jump up to not get hit by a couple of them who appeared to be travelling around 50 miles per hour. The adjacent house had residents returning home that began running from the police. The police ended their sliding perfectly just before a house’s door. One policeman opened the screen door while another shot a bunch of bullets into the door. They kicked the door in and another policeman stuck in an electronic probe to detect explosives, then gave the all-clear signal.
