I think the Avengers could work on the weaponry angle. Maybe they see the reports of the additional violence and start patrolling the ship, trying to head off incidents before they happen? I can see Cap suggesting that to the team. Tony's tech would be helpful for monitoring also. (Watch me volunteer other people's characters, lol.)

And possibly as a way to bring other non-Avengers characters in, they could see the Avengers patrolling and/or help out with an incident and end up joining the group effort?
