What annoys me is the British media (especially BBC News last week) keep alluding to 'lax' security at airports, Turkey in particular.
Having travelled through many airports including both in Istanbul, I have personally never come across security scanners/checkpoints in any country apart from in Turkey that start at the site entrance and/or at the main building entrance (but I'm sure there are some where I haven't been.)
In the UK, USA, Spain, Dubai, Qutar, Singapore, Hong Kong, Dublin, Belfast etc, (unless they have all changed in recent years) the first & only security scan is once you have entered the building, passed through the check-in area and start to go through to the Departures area.
For example, Gatwick = 1 scan/security point before boarding.
Dalaman= 4 scan/security points before boarding.
I know where I would feel safer.
