Well it sounds like we already have two of three boss positions filled, but we need one more and some FBI agents and some gang lackies. On the interest thread, we discussed a few ideas. 

1) FBI agents working with the new gang to bring down the older two.
2) FBI agents working with one or both of the older gangs to drive out the new guys.
3) The FBI creates a "gang" to investigate undercover and bring down the two real ones.

We haven't quite decided what way to take just yet. But give me your input. Maybe we can decide soon :)
