Reports of frequent brutality by Sheriff's deputies against inmates in LA County jails led the Board of Supervisors to a blue-ribbon commission. Last week, the commission's investigators published their findings after interviewing some 150 people and reviewing 15,000 pages of documents. They found that, "harsh force is used as the default position, not as the last resort." They said Under Sheriff Paul Tanaka "promoted a culture that tolerated the excessive use of force." They also concluded that Sheriff Lee Baca "failed to monitor and proactively control the use of force in the jails." Baca's spokesman has denied the claims and said that Baca himself won't comment until the commission itself issues recommendations.
