We do. One of the largest street gangs in the country is the Simon City Royals, a historically white gang that traces it's roots back to the Greaser scene of the 50s. Biker gangs are almost all white. Neo-Nazi skinheads are some of the most dangerous gangs in the world, many literally killing "people" for sport, and aryan white gangs are typically also much more feared than you'd think in prison. Plus as much as Rajeesh likes to make fun of meds aren't white the Mafia is essentially just an alliance of very powerful italian gangs.
What's confusing you is like the Asians and Arabs, White people generally aren't involved in street level crime. But those that are, are often in gangs.
