I tend to agree with Lucifer, ban alcohol sales in airports, Period!
I suspect that many of the low-lifes who cause the problems are alcoholics. "Getting the word out" will do nothing to deter an alcoholic. Removing alcoholic beverages from the airport will go a very long ways to prevent air rage, and LMC. Banning alcohol sales in-flight would go a long ways in preventing problems also.
For the nervous SLF, they can get an appropriate prescription from a physician to handle that. I suspect many alcoholics use their so-called nervousness as an excuse to get "wasted" before/during a flight.
In reality, this would be difficult to put in place, because there is such high profit in alcohol sales, including in-flight sales.
