Terrible. But no doubt ISIS uses civilians as distractions. No way you're going to tell me civilians, on their free-will, are taking cover in buildings with explosives and snipers stationed in it. These people are far to use to war to be doing that.
More than 250 civilians were killed by US-led coalition airstrikes the past month BEFORE this accident.
The truth is that the current conflict is taking place in a highly density area. If you're going to drop bombs on a building, you will kill 5,10,50,100 innocents people with it.
The "they use civilians as human shield" is just BS to keep the moral high ground. Maybe it's true in this particular incident, we will never know. But it's always used to justify US acts of mass-killing. Of course, what would they said ?
I don't say we should just do nothing against ISIS, i am saying that is not the solution. It's a complicated situation with no good solution. But i believe that the worst one is to send those bombs. I rather have a longer conflict which imply more soldiers dying than all those civilians getting killed on a daily basis.
