Personally, I fall in the 'not likely' column, but I do believe we'll see some pockets of violence in the 'resistance' at some point this year.
I am 100% certain that we are already in a civil war NOW. TODAY.
The opening shots were fired in Ferguson, MO and Baltimore, MD. The race rioters are the shock troops.
We are simply now in that phase which was called in 1939-40 the Phony War. Every school shooting spawns an event which could escalate into violence - the Left is gnashing at the bit to be unleashed.
Every social incident (such as somebody being refused service at a restaurant, or being forced to bake a cake) ratchets up the rage.
If you are looking for the answer to when it gets hot, watch for the trifecta to occur:
* a financial panic;
* race riots started by another high-profile incident;
* another mass-casualty event involving firearms.
Look for these, all at once or in rapid succession - the Leftist rage from these will trigger the inevitable.
