Re: snapshot versus screenshot of snapshot
I didn't say the clearance process is perfect. Believe me, I know - I've been through it many times all the way to DV, but it does give the parties that employ persons who have been through the process the confidence that the majority of the people they are employing are suitably trustworthy.
With enough links in any chain, there is always the possibility if not probability that one or more will be weak.
But the background checks, along with the necessary processes should at least be enough to give some confidence that things are handled properly.
And again...I am not suggesting the system is perfect or works without failure.
