Atakacs, your naivety on this subject is evident; security of sensitive information is central to any effective security system - we do not deliberately feed the 'opposition' with valuable insights.
Certainly, we can & should discuss events such as this in the public domain, without revealing detailed aspects of procedure & operations - it is immaterial whether such information could be gleaned from other sources by intelligent & determined research. By observing such 'good practice', we are ultimately looking after our ourselves, our colleagues & the public. A quarter of a century in military service, before my civil aviation career, instilled this in me.
This audacious robbery (I object to the glamourising americanism 'heist'; this was an armed robbery - people can & will be killed in such) could & should have been prevented by a major police presence on the Ramp at the scene, such as I have witnessed at other airports when high-value cargo is being moved.
