At least 115 killed and scores wounded in Moscow concert hall attack

I saw cellphone video last night from inside. There were bodies strewn around the lobby. What is Russia going to do in retaliation? Putin just found out that enemy of my enemy isn't necessarily my friend. I'd like to think, with the 2nd Amendment, had happened in CONUS, It would have been over much quicker with less death and injury.
