About the sixth bus, apparently the sicarios realized it wasn't who they were looking for and shouted: "we fucked up", and the leader replied: "leave no witness alive"

edit: I think it's kind of sad that there's people capable of ending other people's lives just like that, with no remorse, no second thought about it. With that said, many did survive.

edit 2: after re-reading the source I posted below I noticed that I had missed something, he ordered them to go away after shooting (I'm guessing to the sky?). Still, hearing someone order your death, can't imagine how scary that'd be.
