missing the point, again
It seemingly hasn't occurred to these people that "drug dealers ... money launderers, and a double murderer" are the sort of people who will be nervous, but fanatical terrorist would-be martyrs who are about to blow themselves up with you are more likely to be happy, or at least calm & resigned, knowing they're on their way to paradise. Even if their chapatis blow up while they're standing for two hours in Heathrow security, they'll still have done their bit for the cause
I would suggest checking out all the overly-happy holidaymakers, except that would just leave them with a large bunch of 6-year-olds all excited about the aeroplanes. No-one else is happy in an airport these days.
Someday, perhaps, it will dawn on these tax-sucking wastes of space that there aren't enough terrorists in the world to cause even a fraction of the inconvenience and disruption inflicted on us by so-called "airport-security". Terrorists don't achieve their aims by violence, but by using the threat of violence to frighten ordinary people into achieving those aims for them. Airport security today is a perfect example of how Al Quaeda etc. are succeeding beyond their wildest dreams, aided and abetted by the DHS.
And for some vaguely related light relief, may I propose the following Poetry Corner (don't even ask why I was visiting the web site...). It's perfectly SFW, in case you're worried.
