Angels' Night is an event that is an event designed to mitigate criminal acts associated with Devil's Night in Detroit, Michigan. After a brutal Devil's Night in 1994, then new mayor Dennis Archer promised city residents arson would not be tolerated. In 1995, Detroit city officials organized and created Angels' Night on and around October 29–31.
Currently as many as 40,000 Detroiters volunteer to keep the city safe on these nights. Many volunteers keep a high profile patrolling neighborhoods with magnetic-mount flashing amber beacons, on their personal vehicles, along with communicating with command centers via CB radios or by cellular phones to report any suspicious activity.
In recent years, arson and other crimes have declined, much to success of Angels' Night activities and volunteers. The drop in reported fires for the year 2008 has been credited to be because of the Angels' Night program.
