It's a savage affair, & - still - forgive me for being
naturally suspicious about any "official" account of what went
down.
Other than that, I do think the Russians need to relook their whole
strategy of internal security, so that standoffs like the school
&, previously, theater sieges are nipped in the bud as much as
possible. It's plainly a failure of counterinsurgency intelligence,
period.
On paper, their post-KGB security organization appears mightily
bureaucratic: 5 separate agencies, each with its own many
directorates/departments & sub-directorates. Boris Yeltsin's
"democractic" legacy had their security apparatus, along with
countering terrorism, also checking ethnic separatism, labor
unrest, drug trafficking, organized crime, counterintelligence
against foreign spies &, supposedly the bigger priority of all,
the President's political opponents.
