Police car
Police cars are used for chases ("pursuits") against suspects. The crime the suspect is believed to have committed may have been anything from a traffic violation to a major felony. Suspects often attempt to lose law enforcement by driving away, sometimes at high speed. From 1990 to 2005, 136 people were killed in the US in high speed pursuits by police. Despite controversy as to whether high speed chases are necessary police continue to work on the problem using technology and new techniques. One technique is the 'take out'. A take out is a technique used to cause the fleeing vehicle to lose control and be turned sideways by the police vehicle.
