What
@Philim is saying...
Is that since the Big Tobacco debacle, and the issues now swirling around Big Oil, the BoDs, and other alphabet soup titled elitists no longer say anything in the board or other offices where notes / minutes may be taken / things overheard / e-mails un-deleted /phones tapped / board rooms bugged or any other type of ancillary situation or device where evidence may be collected.
From that point forward, the savvy mafia...err...uh - Titans of Industry decreed amongst themselves
Nothing on company electronic devices
Nothing on any company paper.
NO RECORDS!!
Nothing but what is in their heads, or in their carefully hidden personal diary.
So unless you have the abilities and access to pull off the following type of operation you will never find out anything.
So for example - lets take the normal Wed PM OOTO meeting - Golf for an example.
Golf Course - Full access.
Several teams so surveillance can be carried out when line of sight is blocked.
Each team should have the following
Parabolic antennae with mics and recorders
Spotting scope used by a highly competent lip-reader and recorders
Long lens camera w/ video for later analysis.
Automatic cross platform realtime backup to various cloud locations
Spotter / guard to keep your own asses from coming under surveillance.
Coms between teams
Bugs on golf-carts / golf bags / etc
Associated camouflage wear and appropriate locations picked for observation
Multiple escape vectors and vehicles
Etc, Etc, Etc...and a whole lot more if I actually devoted some CPU cycles to the problem, but the brain is nicely idled down for teh night.
So unless you have a black ops team surveilling these guys when they get together "Socially" good luck getting anything.
