The original style of dress was to wear black leather jackets. They walked with a shuffle like a limp and also carried canes.
The Bloods were originally Crip Sets. The Pirus, at one time hung out with the Crips they were called or known as the Piru Street (Boys) Crips. Several members of the Pirus gang had a conflict with some of the Crips and warfare ensued. During the summer of 1972 Robert Ballou, who was not a member of a gang was killed for his leather jacket the Pirus felt that because he was not a member of any organization and neutral he should not have been killed. They got together with the Lueders Park Hustlers, L.A. Brims started in 1969, Denver Lanes, the Bishops. and other organizations targeted by the Crip Sets and formed the Bloods.
Street gangs in Los Angeles had rumbles before this time and were usually over control of parties or hangout spots and high school rivalries. Weapons were not used often, gang members preferred fistfights. It was considered a punk move to get a weapon to retaliate after a fight. The most common weapons included baseball bats, bumper jacks, or an occasional knife.
