"The ability of specially selected and trained SROs to establish trust relationships with students has been demonstrated to prevent school shootings.In addition, there have been numerous documented instances of SROs directly intervening to prevent or quickly mitigate active school shootings."
That's a quotation from a new report from the U.S. Department of Justice Office of Community-Oriented Policing Services (COPS Office). The report, Ten Essential Actions to Improve School Safety, also recommends that the selection, training, and supervision of SROs should comport with NASRO’s Standards and Best Practices for School Resource Officers. "It is essential that an MOU be put in place between the school or school district and the law enforcement agency providing the SRO(s)," the report continues. "Among other things, the MOU must clearly stipulate the SRO’s role especially with regard to enforcement actions."
