The Rollin 30's Pirus also known as Blood Stone Piru (BSP) is a Piru street gang based in East Los Angeles. Although they claim Piru, they have no affiliations with any Compton Pirus (P-Funk Ridas). The gang has been active for nearly twenty years, and though small in number have held their territory. They fall under the Rollin O's (Bloods) umbrella alongside gangs such as the Rollin' 20's Neighborhood Bloods, Rollin' 40 Pirus, & Outlaw 20's Bloods. They are rivals to several Neighborhood Crips (2x) Rollin' O's (Crips) street gangs as well as all Gangster (3x) Crips sets.
