Coming out to fight is just what the bastards want them to do. Re-imposition of martial law because of a threat to law and order will have the army back in control faster than you can blink. I think MF are more clever than that and know a better way to turn the situation, but don't discount violence from the other side if it looks like Pita is going to win.
For the powers that be - there's too much riding on this. A move towards a democratic state with reforms to the monopolies etc. is going to p!ss off a lot of influential people.
This can't happen overnight without some compromises however difficult and distasteful that might be.
