Their bodies are also often marked with tattoos that are generic prison symbols that you will find on just about any inmate.

This cryptic tattoo is gang code for "East Coast Crips." In this case "East Coast" does not refer to the Eastern seaboard. It means "east" of the 110 (Harbor Freeway), which runs north to south through Los Angeles. The tattoo depicts an "E" and a convoluted hand sign for "C." Incidentally, this gang was featured in Michael Jackson's "Beat It" video. PoliceMag.com gang specialist Richard Valdemar transported them to the set.

Tattoos of the Bloods are pretty basic. You will see P for "Piru" or B for "Blood." Another popular Blood symbol is CK. This can stand for "Crip Killer" or "Cop Killer."

Many non-Crip gangs formed a coalition opposed to the Crips, often using the names Bloods or Pirus.

The Crips are not very imaginative with their tattoos. Their most common symbols are the letter C for "Crip" or BK for "Blood Killer."

This tattoo signifies a Pasadena Denver Lane Blood. The fingers are curled to create the "B" for Bloods. The Denver Lanes were a Pasadena gang that joined with other non-Crip gangs to oppose Crip gangs.

Rapper Snoop Dog is closely associated with this gang, although he is actually a Rollin' 20's Crip.
