I see shoot to kill happening.
In a sane world it would have been in place for most of the recent riots. I have trouble seeing Obama and company sitting on the sidelines if it does occur - there is way to much for them to leverage with the MSM and every Leftist group in the world howling for him to "quell the evil ones defending themselves and others". I would guess we would get a taste of martial lawless stepping on decent citizens and it would be used as a training session for future "necessities".
If it occurs, it will definitely be interesting - especially for the poor folks caught in the middle and those who are of a mind that now is the time to send the government a concrete message. I'm safe in S. MS (whodathunkit) and can view from my living room.
On the bright side, it would certainly allow Cruz to do some more shining....I would gladly follow such as he into battle.
