A Las Vegas police officer has been demoted after failing to stop the death of an unarmed black man. Now former sergeant Travis Crumrine was in charge of officer Kenneth Lopera during the death of Tashii Brown last May. Lopera shocked Brown multiple times before placing him in an unapproved chokehold. Records show that originally, department officials accused Crumrine of failing to intervene by not ensuring that Lopera let go of Brown after he gave the officer an order to do so. Ultimately, Crumrine was demoted to police officer on Nov. 1 for neglect of duty and for failing to turn on his body camera during the interaction.
