My bet is that one of the fathers of the Russian children did it...

The controller in this case clearly screwed up since he instructed the
Russian jet to descend when the Russian crew told him they had an RA
instructing them to climb.

Did they really?

Controllers are required to instruct
flight crews to follow the RA when an RA occurs,

They are not.

and crews are
required to follow the RA.

Yes, they are.

The Russians don't appear to have given
proper training to their crews regarding the TCAS system because the
crew didn't ignore the controller like they should have and followed
the RA.

Yep.
