VIDEO: Animation of 2012 Cleveland Police Chase, Shooting

A video animation shows the end of a November, 2012, pursuit in Cleveland, Ohio, where 13 police officers engaged a fleeing vehicle with 137 shots, killing a male and female suspected of being involved in drug activity.

A USA Today report details how Cleveland police officers began pursuing the vehicle carrying the pair at about 10:30 p.m. on November 29, 2012. Authorities suspected the two were involved in drug activity and at some points, the car is believed to have backfired, causing several officers to think shots were being fired at authorities. Police did not find a gun in the car and those close to the pair say they don't know why Russell didn't stop the car. In the end, Russell, 43, the driver, was shot 23 times and passenger Malissa Williams, 30, was shot 24 times.

This year, the Cleveland police department adopted a restrictive police chase policy: officers can only chase those suspected of a violent felony or driving while intoxicated. The move is part of a growing national trend among departments to limit chases, experts say.

Every chase comes with the risk of hurting innocent bystanders and destroying property in accidents. While concern about chases has gone on for decades, in the last few years, more and more departments have been reacting to such incidents by changing the rules officers follow, experts say.
