Devil's Night is a name associated with October 30, the night before Halloween. It is related to the "Mischief Night" practiced in parts of the United States such as Philadelphia but is chiefly associated with the serious vandalism and arson seen in Detroit, Michigan, from the late 1960s to the 1990s, finally prompting the "Angels' Night" community response. Description Devil's Night made its way to Detroit in the 1930s and 1940s. Traditionally, city youths engaged in a night of mischievous or petty criminal behavior, usually consisting of minor pranks or acts of mild vandalism (such as egging, soaping or waxing windows and doors, leaving rotten vegetables or flaming bags of canine feces on stoops, or toilet papering trees and shrubs) which caused little or no property damage. By the 1970’s, the concept of Devil’s Night as a phenomenon of a night of mischief and vandalism had spread, in a limited way, to cities around the state of Michigan, around the Midwest, and, in some instances, a few other cities around the country. However, in Detroit in the early 1970s, the vandalism escalated to more destructive acts such as arson. This primarily took place in the inner city, but surrounding suburbs were often affected as well. The crimes became more destructive in Detroit's inner-city neighborhoods, and included hundreds of acts of arson and vandalism every year. The destruction was worst in the mid- to late-1980s, with more than 800 fires set in 1984, and a number in the hundreds for each subsequent year until 2011. Decline of Devil's Night arson Devil's Night arson in Detroit had not declined by the early 1990s. After a brutal Devil's Night in 1994, mayor Dennis Archer promised city residents arson would not be tolerated. In 1995, Detroit city officials organized and established Angels' Night on and around October 29–31. Each year as many as 50,000 volunteers gather to patrol neighborhoods in the city. Many volunteers kept 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. Incidences of arson and other crimes declined, a success largely attributed to the Angels' Night volunteers. The drop in reported fires for the year 2008 was credited to the Angels' Night program. That same year, 35,000 signed up to volunteer in the city, according to Daniel Cherrin,
