Legal experts say the officers involved in Taylor’s shooting – Sergeant Jonathan Mattingly and officers Brett Hankison and Myles Cosgrove – certainly can be arrested. Prosecutors wield tremendous discretion in their decisions to bring charges, and “probable cause,” the legal standard of proof needed for an arrest is “an exceedingly low bar”, said Colin Miller, a professor at the University of South Carolina School of Law researching the Kentucky criminal code on behalf of lawyers representing Taylor’s family. “If you have a shooting death, it’s going to be pretty difficult to argue you can’t at least charge some type of crime in that case, whether it be endangerment manslaughter or murder.”
