AB v. County of San Diego
In AB v. County of San Diego the decedent was handcuffed, hog-tied, hooded in a bloody spit mask, and subjected to 7 minutes of forceful prone restraint by several officers who pressed their knees and fists down on his back. San Diego county's designee admitted at deposition that officers received no training on asphyxia, and were in fact affirmatively encouraged to use substantial body weight on a prone subject to achieve compliance with verbal commands.
