Street Gang Signs and Symbols

I found a website on street gang signs and symbols.  This website tells how symbols and signs are a big part in gang culture.  Signs and symbols represent a particular gang and is often used to tell them apart.  Some signs and symbols represent one individual group but others can represent an alliance of gangs that they sometimes call a nation.  Some signs or symbols can be as simple as a pyramid others can be something drawn or made up.  On this website you can see some examples of what some of these symbols look like.  I think that in some ways it is good that gangs have different symbols because since they represent themselves with these symbols they most likely will have them written or worn somewhere on their body.  This makes it more helpful to know who is part of a gang and to which one they are apart of.
