In a word, "Yup."
If these people have knowledge of a crime, aren't they legally obligated to report it to law enforcement?
Normally, one could claim no knowledge of a crime but in this case, they have announced that they have knowledge of crimes.
Depends on the laws in their HQ location, but in most civilized nations this is called extortion by Hold Security. They are most likely in the cross hairs of law enforcement as I type this. If this turns out to be a bogus or inflated claim (like it smells) they could face some serious criminal and civil charges, regardless of what country they are in.
Here's a question. What would happen if the beams traveled different distances? AKA, one beam took longer to reach the recombinator than the other. I can guess, but I have no clue about Quantum Mechanics.
So, go read more about the subject in your free time. There are s of freely available publications that cover the topic. I am not certain that the experiment would yield anything based on your hypothesis, not even the results being discussed. The most quantum experiments are predicated on a very specific set of conditions and why it hasn't been done before, accurately.
