They Don't Talk About Missing Members
The Hells Angels are extremely secretive, especially when a member of their charter or group goes missing. They do not discuss anything about that missing person to the outside world, and it's assumed that members themselves don't even speak about them.
The Rules of Meetings
The Hells Angels follow a rule system called Robert's Rules of Order. The members stick to the plan, they do not interrupt one another when speaking, and they can only ask questions before the meetings begin. If someone doesn't respect the rules, they can be fined a monetary charge.
