Also see Brazil with Primeiro Comando da Capital and Comando Vermelho which are violent organizations that have/had lofty goals similar to the growing movement (i.e. anti-police brutality, vengeance)[1]. Those groups now partake in degenerate drug and sex fueled parties and slaughter their enemies using advanced weapons. No need to worry though; their code of conduct proclaims that they fight for liberty, justice and peace and that rape is bad -- they're obviously the good guys.
