[Butch Cassidy Slept Here]

charges of assault, breach of peace as well as non-compliance with aviation laws,

If the charge of assault is legitimate, as opposed to a "cover charge" (a fabricated charge filed to "cover" illegal conduct by law enforcement authorities,) then he deserved what he got. I'm somewhat inclined to believe the airline's side of this story--and no, not because it's Lufthansa. At some point, prior to being kicked-off the plane, this man may have identified himself as a figure in Polish politics. Since this was Lufthansa, rather than the domestic carrier, LOT, the Lufthansa crew may have felt some obligation to be extra careful not to do or say anything which could be construed as over-reacting. Finally, if the cops are able to get a blood, urine, or breath sample suggesting (alcohol) intoxication, this guy is--as flight attendant PHXFlyer likes to say--TOAST!
