Only 1 post from you in this thread? Surely you have more to say 
first, I have a 1:30 am meeting.....
gotta let the investigation play out . I have a lot to say but not all for public consumption.
I was simply commenting that to cast aspersions on the OKs overall integrity over this, is hogwash.
This could have happened to any hashgacha I know , chasidish, litvish, national, local Va'ad.... Of course you have to do due diligence in prevention but as stated earlier , nothing is fool proof. Obviously you have to learn from mistakes and not repeat them.
One possible prevention method is to use signed & numbered single use zip tie seals in conjunction with locks.
Good quality, hi res cameras are a must nowadays.
Ultimately,, if someone wants to cheat , no amount of mashgichim will stop him. Only siyata dishmaya will help catch him. (Locks are for honest people). We recently gave hashgacha to a certain establishment but realized we couldn't trust the management even for silly things and ultimately dropped the hashgacha shortly after the grand opening. We took a lot of heya for that decision but we're ultimately vindicated when the new certifier caught them sneaking in specifically rejected product in garbage bags.
There have been several insane scandals by other agencies in the recent years months (some are ongoing) that are simply brushed under the rug. R Yudel is aware or willfully ignorant and therefore his word carries no weight.
Last point for now....a chain is only as strong as it's weakest link. You can have all the safeguards in place but if the Mashgiach isn't following protocol, it's worthless.
That why it's if utmost importance to have someone checking in on the onsite mashgichim at least twice week but preferably everyday to provide support, supplies, and to ensure the mashgichim are on their game. You can't park a Mashgiach somewhere, forget about them and assume all will be well.
I've see a situation multiple times where a Mashgiach comes in for a morning shift and finds an issue in the sealed walk-in.
Or vice versa where a Mashgiach simply opened a sealed walk-in without verifying the contents or a Mashgiach in a supermarket who, when following the strict protocols to check in all incoming deliveries, checked in and signed non kosher product.
