This photo shows a police officer [a swat team officer] covering the back entrance of a resident as a drug raid was in progress. It shows how well prepared the officers are in full dress and equipped with a tear gas launcher. The rear bumper of his unmarked van was used by the officer to stand on and view over the fence. Swat teams train for the worst case scenario. The police had called 911 and a swat team was called to the scene. The other officers of the swat team were covering the front and sides of the domestic residence. The letters swat means (special weapons and tactics). A swat team is an elite unit within a police force. The officers in a swat unit undergo special training and have access to weapons, armor and surveillance devices.
