 Since 2014, PERF has focused on developing policies and training programs to minimize police use of lethal force, particularly in situations involving persons with mental illness, developmental disabilities, drug addictions, or other conditions that can cause them to behave erratically or dangerously, and in situations where the subject does not have a firearm.PERF also has released a series of reports describing and advocating the increasing role of local law enforcement agencies in addressing the opioid epidemic, by actively helping addicted persons to get treatment and other services, while saving lives by providing naloxone to officers so they can help prevent fatal overdoses.PERF also has reported on police leaders’ approach to immigration issues and has researched police programs to welcome refugees to American communities.
