Yeah, or remove the factors that allow them to exist. Drug legalization, for example, would weaken street gangs like crazy.

Sounds like OP has some beef with street gangs maybe? Planning to go Charles Bronson on us huh?

I'd like to point out gangs will never be eliminated. People are always stronger in groups. Did you know Irish gangs used to fly red and blue colors back in the 1850's?
