Clinton has made addressing police shootings and criminal justice reform a key aspect of her campaign

(CNN) Hillary Clinton's campaign manager said Wednesday that the Democratic nominee would implement a set of best practices to prevent police-involved shootings like the ones this week in Charlotte, North Carolina and Tulsa, Oklahoma.

"There are two prongs to her approach," Robby Mook, Hillary for America campaign manager told CNN's Alisyn Camerota on "New Day." "The first is to have a set of national standards around how to manage the situations that doesn't exist right now and that could help through training to prevent situations like this."

"There are no set of national best practices on how to manage situations," he continued. "These situations are handled by local policies currently. And what she is proposing is that we actually set up national standards so that localities have better policies to work with and train towards."

Clinton spoke out Tuesday against "systematic racism" following the recent shooting of Terence Crutcher in Tulsa, Oklahoma. Crutcher was shot and killed last week after his car broke down. The 40-year-old black man raised his hands above his head just before Officer Betty Shelby fatally shot him. Crutcher was unarmed at the time.
