Guardian Angels first made an appearance on the New York subway in 1979 in an attempt to quell rising levels of violence. As in all of New York, crime was rampant in the subway in the 1970s. Thefts, robberies, shootings and killings became more frequent. The subway cars were very often graffiti-painted or vandalism-damaged both inside and outside.
As the New York City Police Department was completely overwhelmed, the public reacted with unease, and the subway was deliberately avoided. Around 1980, the reliability of the vehicles was a tenth of their reliability in the 1960s, and 40 percent of the network required speed restrictions.
