Houston City Council is expected today to consider an usual $260,000 settlement following a series of federal court rulings that sided with father Audry Releford in his lawsuit over the shooting death of his son, Kenny, by a Houston Police Department officer.It's by far the largest settlement to be reported in any case involving an unarmed person killed by police in Houston in years — but the lawsuit separately marks a kind of turning point for local civil rights leaders who described it as one of several controversial cases that boosted public awareness about police use-of-force and weaknesses in HPD's reviews of officer-involved shootings.
