I have never been affiliated with a gang.

However, in my job, I'm an investigator, and in some cases, gangs have been involved in the identification of offenders in the criminal investigations we've done.

I definitely research a lot about domestic gangs to help me with my career. It's good to know about criminal organizations when you're involved in investigations.

In college, I majored in counterintelligence and anti-terrorism. Some of the foreign gangs were often subjects I wrote papers about. A lot of cartels and mafia-type organizations got drugs and weapons into the States.

Again, it's definitely a good idea to keep some factsheets on these folks.
