Allentown's crime statistics are heightened significantly by gang-related crime and gang rival and retaliatory violence stemming from the presence of many of the nation's most violent gangs in the city.[47] In the 1990s, anti-gang initiatives in New York City and elsewhere resulted in an increased population of gang members in Allentown, particularly in the city's center city area.[48] Gangs including 18th Street, Black Dragons, Bloods, Crips, Latin Kings, Los Solidos, Mexican Mafia, MS-13 all have a presence in the region.[48] Over 75% of the homicides in Allentown during 2007 were drug or gang-related killings.[47] In 2008, a multimillion dollar methamphetamine ring operating in Allentown and the surrounding region, with ties to the Crips organization, was broken up by narcotics agents.[49] The city has undertaken various initiatives, including participation in the federally-funded "Route 222 Corridor Anti-Gang Initiative" and the reorganization of the city police department, in an attempt to combat the problem.[50][51]
