Abstract
The purpose of the Fellow Law Officers Encounter Warning System (FLOEWS) is to apply infrared signal technology to provide an advanced real-time early warning response to police officers who encounter a fellow off-duty-plainclothes or undercover officer during their response to the commission of a crime, to provide off-duty-plainclothes and undercover police officers with a layer of safety as they carry out their duties as police officers, and ultimately to prevent the circumstances surrounding friendly fire.
Description
- Not Applicable
- The development of the FLOEW System utility, described in this application, received no federal sponsorship; therefore, no rights are afforded to this invention under the federally sponsored research and development program.
- Not Applicable
- An old police tradition of requiring off-duty-plainclothes officers to carry their weapons—“always armed, always on duty”—is being scaled back in police departments nationwide following the shootings of off-duty officers by colleagues who thought they were criminals. The policies require officers to respond to crimes even when they are not on duty. Supporters say the tradition also protects officers from criminals bent on revenge. Nevertheless, critics point to the shooting of officers in Oakland, Providence, Orlando, Fla., and elsewhere as reasons for change. Providence's policy is now at the center of a $20 million civil rights lawsuit over the shooting of an officer who was killed while off duty and trying to break up a fight. He wore baggy jeans, an overcoat and a baseball cap, and carried a gun. According to the FBI, 43 police officers have been killed since 1987 by friendly fire. In 2001, two uniformed officers shot and killed an undercover detective when he pointed his gun at a suspected car thief in Oakland. In January 2006, an off-duty-plainclothes New York City police officer, who drew his weapon to defend himself against an assault by several men, was shot and killed by a fellow officer.
- The International Association of Chiefs of Police has called “always on duty” policies a costly tradition. The group, which has more than 20,000 members, recommends that off-duty officers who witness a crime call for assistance rather than draw a weapon.
- In Providence, carrying a gun is now optional for off-duty officers, who are encouraged instead to be good witnesses if they see a crime. The police unions in Washington, D.C., succeeded in securing similar rules after three off-duty officers were killed in separate incidents. The Los Angeles Police Department allows its officers to carry their weapons off duty but doesn't require it. The trend of Law Enforcement Agencies to scale-back or rescind the “always armed, always on duty” policies will have a negative impact on the law enforcement capability and ultimately public safety.
- The FLOEW System is a real-time alert system that uses Infrared (IR) signal technology to provide uniform, off-duty-plainclothes, and undercover police officers with a preventive measure against police (typically uniform) officers who mistakenly fire-on fellow officers while responding to the commission of a crime—friendly fire. The FLOEW System provides police officers with an advanced alert of an impending fellow officer encounter, more specifically, that their firearm has been drawn against an off-duty-plainclothes or undercover police officer who has responded to the commission of a crime. The FLOEW System allows off-duty-plainclothes and undercover police officers to continue to provide the maximum level of law enforcement capability to ensure public safety; while providing them with layer of safety against friendly fire.

- Off-duty-plainclothes and undercover police officers who respond to the commission of a crime do so under the constant stress and threat of being shot by an ensuing fellow officer. Although police officers are trained to yell “police!” when they draw their weapon during the commission of a crime, environmental noises may cause them not to be heard, this leaves the potential for friendly fire accidents to occur. The purpose of the FLOEW System is to provide an advanced real-time early warning response to uniformed police officers who encounter a fellow off-duty-plainclothes or undercover police officer during to the commission of a crime. The goals of the FLOEW System are to alert police officers, warning them of the impending fellow officer encounter and ultimately avoiding friendly fire. And, to avoid the emotional pain and suffering of families, and the financial liability to municipals that result from fatal law enforcement friendly fire accidents.
