I'm seeing what's missing from it, which makes the argument very weak, if not null. That does not mean I know if it happened or not, but the motive is evidently stronger for the Jihadis to have staged it, and that is my issue with your argument - that you take the time to suggest weak explanations of why Assad might have done it, but I have not seen you admit that the Jihadis have a far stronger motive.
Think it through - how do these terrorists fight in cities these days? Do they come in 4x4 troops blaring their horns and firing their rifles as they used to in the past? Or do they discreetly gather little by little in pockets of cities, merging in with the rest of inhabitants, and then once they have brought in enough weapons and ammo, they take women and children as hostages and launch an assault? De facto, the government forces are going to lose ground immediately when that happens, until the surge is repelled. The bigger picture is that every time this happens, Assad's forces are winning every single battle.
