Before getting into tracking databases, passport stamps, legislation etc for air ragers (is that a word?) It may be useful for all concerned to think about what the problem is and whether thereis not adequate means currently available to control it.
1. All the activities that "real" air rage involves (threats to do thus and so to the A/C, keeping the crew from doing their jobs, assulting crew and/or passengers, carving one's initials in the seat etc.) are against current law or regulations, at least in the U.S. Maybe recodifying all the provisions in one place in the statutes and one in regulations could help, but I don't think new laws or rules are needed.
2. The alcohol question is really easy...if they are drunk don't let them on, if they start to get drunk cut off the alcohol or whatever other thing they are getting drunk on. I know some drunks are "happy drunks" and some drunks are "mean drunks" but the common denominator is they are all drunk and out of control and that has no place on an aircraft.
3. The post re the Delta flight and Republic of Ireland is an excellent example of why more draconian rules, "guilty until proved innocent" procedures and such are not necessarily useful.
Lets figure out a common objective definition is of "air rage" (a poor term coined by the tabloid press I bet) in the different countries and maybe ICAO will start keeping track of it.
