In any event, it doesn't look like the Russians were expecting to storm the building. Their perimeter wasn't tight, and some terrorists managed to slip away in the confusion. Also, the emergency response was haphazard, leading me to believe that they weren't expecting to deal with a large number of wounded right that second.
Russia certaintly needs to revisit its tactics in dealing with terrorists. Maybe draft an actual terrorism policy instead of this trial by error they've been using lately.
