The U.S. Supreme Court is set to consider on Wednesday a woman's civil rights lawsuit over the fatal police shooting of her son during a traffic stop in Houston in a case that could make it easier to hold officers accountable for using excessive force.

A manhunt ended in Texas when a Houston man accused of shooting and killing a deputy serving a warrant on him in the parking lot of a Dollar Tree, was fatally shot by police.

Ashtian Barnes, an unarmed Black man, was killed by an officer in 2016 after being pulled over outside Houston while driving his girlfriend’s rental car, which had unpaid toll fees.

How the Supreme Court decides the civil rights issue could affect how readily judges dismiss suits against police for improper use of deadly force.
