25 Notoriously Dangerous Gangs

Posted by on January 26, 2012

In the past we took you to the 25 most dangerous cities on Earth, but now we’re going to take a closer look at one of the biggest reasons those cities are so dangerous – gangs. With everything from street gangs to prison gangs to international crime syndicates this list will take you on a journey through a violent criminal underworld as you are introduced to 25 notoriously dangerous gangs.


Jamaican Posse

Known to have an affinity for high powered assault rifles, the Jamaican Posse is well connected in the island’s government and heavily feared for its practice of ritualized killing that often involves laundry irons, butchers knives, and even vacuum cleaners.


Primeiro Comando da Capital (PCC)

Found throughout the Sao Paolo prison system in Brazil as well as its numerous favelas (slums) this gang is known for kidnapping, extortion, and its ability to instill fear. In May 2006 it managed to put the entire city of Sao Paolo under siege for almost a week while gang members brutally killed police officers and burned government buildings.



What started out as local gang of 16 year olds turned into one of the biggest crime organizations in the world. As bitter rivals with both the Bloods and numerous hispanic street gangs the Crips are known for wearing the color blue and carrying out extreme acts of violence. They are so violent in fact, that many of their casualties are the result of infighting and internal conflicts.


Aryan Brotherhood

Responsible for roughly 1/4 of prison murders in the United States, if you want to be a member of this gang you must kill or assault a fellow prisoner. It is a practice known as “blood in, blood out” so anyone who tries to leave the gang usually ends up dead or in the hospital as well.


La Nuestra Familia

As one of the biggest Chicano gangs in the world it is also bitter rivals with its fellow countrymen in the Mexican Mafia (#18). In fact, La Nuestra Familia is said to have started when a member of La eMe stole a fellow Latino’s pair of shoes. This gang is known for requiring extremely strict allegiance and it takes over two years to be fully initiated. Once you are in, though, there’s no turning back.
