3:05 p.m.

A North Charleston police lieutenant has testified that neither a baton nor pepper spray would have been effective in trying to stop Walter Scott as he fled from a traffic stop.

Walter Humphries testified Monday at the murder trial of Michael Slager, the white former North Charleston patrolman charged in the April 2015 shooting death of Scott, who was black. Scott was shot five times in the back in a shooting captured on cellphone video that was shared on the internet and stunned the nation.

Humphries testified that because Scott was running away, a baton would not have worked because officers are taught to use a baton to hit someone's legs. He said pepper spray needs to be sprayed in someone's face.

Humphries was asked whether Slager should have just given up the chase. He testified that's always an option but that he wouldn't want an officer who just let a suspect go to be working for him.

Four North Charleston officers testified at Slager's trial on Monday.
