it doesn't take many armed and dangerous men, .just a few will be very effective
there are plenty of people with training or that are still in the military, (and other, sensitive areas) that will be a real problem if the regime continues the current path...it seems they want to provoke a reaction - they seem to think that the people who are going to lead the fight are lead by emotions like the political base, but that is a miscalculation  

many young men are out there unmarried, with no prospects of a family...nothing to lose:  a suicidal attacker is extremely hard to stop - there could be middle east style violence - maybe that will be an excuse for more government and more surveillance
