How not to demonstrate someone's innocence

When 11 people are arrested for spying, and their names have not all been released yet, and furthermore some of those released are U.S. citizens, it would probably be prudent for the foreign service of the country they're accused of spying for NOT to demand access.

And yet, the Russian foreign service has demanded access to the 11 arrested and proclaimed their innocence without even knowing for certain their identities, and despite the fact that at least a couple are not Russian citizens.

Translation: G-U-I-L-T-Y. We'll see what the courts say, of course, but this (inadmissible in court) piece of evidence suggests that the reason the foreign service wants access is because they need the last bit of data from these people before they visit the graybar hotel for a good long time.
