Probably because the "expert inspectors" don't know what fermentation gear looks like. I've contacted the FBI re: other scientific matters and was blown off by an agent who likely never did, could, or would complete a Ph.D. program at a top-drawer research university. To the Gummint, we're all just a bunch of idiots -- unless we have taken our B.S. in accounting and completed an 11-week agent training course at the FBI Academy and then "get to" tote a badge and under-cleaned semi-auto in an inappropriate holster......
But, then again, that's just my opinion.... 8~)
