Abkürzung für Law Enforcement Officer
LEO ist mir in der US-Kriminalliteratur schon öfter begegnet.
"I took a chance that you’d come in at night. It’s how we LEOs catch perps: people like their routines.”
(Sara Paretsky: Fallout, p. 195)
»a public-sectoremployee whose duties primarily involve the enforcement of laws. The phrase can include police officers, municipal law enforcement officers, special police officers, customs officers, state troopers, special agents, secret agents, special investigators, border patrol officers, immigration officers, court officers, probation officers, parole officers, arson investigators, auxiliary officers, game wardens, sheriffs, constables, corrections, marshals, deputies, detention officers, correction officers, and public safety officers (at public institutions). Security guards are civilians and therefore not law enforcement officers, unless they have been granted powers to enforce particular laws, such as those accredited under a community safety accreditation scheme such as a Security Police Officer.« (https://en.wikipedia.org/wiki/Law_enforcement...)
