I travel with valuable items from time to time and we are very twitchy around the screening zone. They are concerned about their 'process' and consider that paramount.
sadly it does not take into account items a traveller may equally have concerns about.
I never take my eye off a bag and will not enter a screening arch until my bag has entered the xray tunnel.
I will not face away from the baggage belt. And you fail screening you can refuse to have your bag opened and searched in public, there will be facilities for private screening.
Unfortunately at provincial airports this happens rarely, so the commotion caused by requesting it raises a fair bit of attention.
Busy international airports are familiar with it as routine.
