Who is on Drugs?
Mr Hat.
I can assure you that train drivers, doctors, bus drivers and even the odd lawyer in the transport industry is subject to Drug and Alcohol testing.
Saw a legal eagle summarily dismissed because of imbibing a couple of beers at lunch and then returning to his (transport) employer. Biggest mistake was going back to work!
The whole security issue revolves around managing the risks. The incidence of 'terrorist' events around aviation is miniscule compared to the total overall activity in the industry sector.
If the objective of 'additional security' is to curtail the terrorist's options, then the sarin episodes in Japan, the bombings in Madrid and London should have had the same overlay of 'security response' as is now imposed at airports. Didn't happen did it - well at least not to one of the 52 'free states'.
You are NEVER going to be able to completely cocoon aviation from threats - if in fact the threat exists in any real magnitude. While a certain superpower fails to recognise that those who oppose it have intelligence also, we will always be in a cycle of knee-jerk, populist catch-up responses to events as they occur.
I was given a piece of sage commentary recently. Years ago you could ride a motorbike without a helmet. Then to make it 'safer' helmets became law. Bikes got far more powerful. Net result. Helmet just keeps the bits all in one place when the bike and rider part company. Hasn't stopped the event happening, but has sure removed one of the joys of riding. Much the same issue with aviation.
