Why is it necessary for police to 'swarm' a location after the action is over? Is it a way for them to avoid police work while pretending to be doing something? Is it just to impress the TV cameras that they are on the job--right there as soon as there's nothing they can do to help?Twice in one month, Casselberry police had to swarm the Shoot Straight gun range because someone was killed inside. This time a man from Winter Springs shot himself in the head and died.
