Guys,
Financial institutions have a legal obligation to insure all monies during transit. This is an obvious stance of course but these requirements instill work ethics and 'covering your back exercises'.
If a discreet/ low profile method of operation was employed it is fair to say that the overt in your face armoured vehicles, helmets and so on would not be used. If money went missing as a result of an attack then the obvious questions would be asked.
In theroy, low-profile CVIT does make sense but in reality, it would take more manpower (utilising decoys and counter-surveillance and also an SAP). With serious and well trained professionals, it could work.
In practise, it wouldn't be feasibile due solely to the insurance aspect and concern.
In practise, it wouldn't work as highly trained individuals or rather, the skills required are simply not found in the employ of the CVIT industry.
Valuables that are privately owned could present a market but this would be so niche that it wouldn't be worth entertaining in any great shape or form.
