Kasparov's aide and PravdaBeslana.ru founder Marina Litvinovich has posted recordings of the walkie-talkie conversations between OMON fighters - on April 14 in Moscow and on April 15 in St. Pete.
On Radio Echo of Moscow, they've been playing one of these clips all day long today, the edited copy, with beeps instead of the curses.
There's also this thread on RadioScanner.ru forum, where the folks were listening in on the police during the rally in Moscow:

A quote: "There's no one on Rozhdestvenskiy Boulevard! Not a single person, only OMON. Who are we supposed to detain, damn it?!"
Ivanov, April 14, 2007, 13:03:21 -
And in reply - "Detain everyone - with or without the attributes - detain them all!"
They'll have to detain the OMON guys :)))
