Abstract For decades, extremist groups in the U.S—particularly on the far-right—have encouraged their members to infiltrate law enforcement agencies and the military. While there are anecdotal examples of insider threats in law enforcement, we do not have a systematic understanding of whether these are isolated incidents or indicative of a more pervasive issue. It is not feasible to examine officer-level risk of engagement as an insider threat at this time. Surveying police officers is a difficult endeavor due to access issues, intense public pressure and skepticism about participating in research, social desirability bias in answers, and lack of generalizability.
