Take your boots off: an idea on being prepared at the airport

It always surprises me when I get to the security line at the airport and see people that are not prepared.

The Classic example:
Slowly putting personal effects out on the conveyor.
Forgetting to take out electronics.
Keeping belt on.
Leaving change in pocket.
Not taking boots off.
Forgetting about that bottle of water in bag.
Asking if the security person can allow said bottle because it was just bought.

Seriously, don’t people read signs? Don’t they know by now that liquids and weapons sharp objects are not plane friendly?

Ok this post is not meant to be a rant. (although travel stories would make for a rather entertaining read).

Alternatively, I’d like to propose a solution: a Nexus-like program for security.

Nexus (or Global Entry for other countries) allows frequent travelers to bypass long passport/immigration control lines.
By simply signing up, paying a fee and satisfying certain requirements (one of which is an interview), users gain the added benefit and freedom of “skipping” the line.

Wouldn’t it follow suit that you would have a similar program for security lines?

Like a driver’s test, the program would seek to educate and enforce security protocols by rewarding compliance and efficiency.
The awarded badge would allow access to a different “express” security line where all travellers would be experts at being processed.

Result? Better experience, enhanced processing, new revenue stream: seems like a good idea to me.
I'd pay for that!

Thoughts?
