Crystal ball....?
This reminds me of a story..
I was at a facility that was soliciting future .gov business (long range precision rifle stuff for guys working down range). The owner was saying some incredible stuff in regards to abilities and a particular rifle's round count with apparently no measurable wear and world class groups on a regular basis..
Lots of guys kept looking back at me, waiting for me to throw the BS flag, but I was biting my tongue, as argument was pointless and knowing my boss would prefer that I just be polite, professional and most importantly, be quiet.
The real gem was when the owner said that tier 1 group xxx trained at his place. Little did he know, a number of people he was speaking directly to were recent former members of the that organization. To be clear, I'm not a former or current member of the organization.
Anyways, after glances exchanged, and a break occurs, phone calls were made and nobody knew anybody from that unit that had trained there, either individually or as a unit.
Pays to know your audience.
We were locked on to do a mandated course there, ( however a former SOTIC instructor now working for our organization was the primary instructor and made the best of a crap situation) but shortly thereafter the program got moved to a more suitable location. This one did not have self anointed experts, but actual guys with credible backgrounds..
