Again I totally disagree. Live in S E Asia where punishment does fit the crime and the same drunken louts soon learn to behave themselves.
Despite cheap booze, street crime is quite unusual, drunken acts on aircraft, again very rare. These same louts do come here too. Difference is, they KNOW their behaviour will NOT be tolerated. Step out of line and the will be slapped down hard.
McClaren found that out the hard way!!
