Were the civilian casualties in Mosul something other than the usual collateral damage?

This.

Due to US propaganda people* thought* that the Americans only did ‘clean’ air strikes. Now they know they are as sloppy as the rest and the Russians are not much worse then them.

Well, the military is prepared to admit they “probably” had a role in those casualties:

However, the civilians “probably” died not because of bombs raining down on their heads but because ISIS knew this strike was coming, gathered the civvies there and wired the place up with explosives that would detonate when hit by a US precise strike munition. Seems legit…
