As long as the undercover cop isn't the one leading the gang and threatening violence towards anyone that doesn't help commit crimes, it's likely not entrapment. Entrapment almost always falls under a crime that you otherwise never would have done if a cop didn't somehow coerce you to do it. I'm sure there are some grey areas like a cop offering a homeless person some drugs to sell or telling a lower ranking gang member to commit a crime when knowing that they may be harmed if they refuse. But simply participating in illegal activities that would be taking place regardless of the undercover's presence is not entrapment.
