the mayor's comment about getting back safe and the vinci police brass with their ominous/weighty facial expressions (which seems to be a permanent affliction for them)...

I guess the assumption was that it would just be Ani/Velcoro and riggins and it wouldn't spill out into the street like that.

Ain and Velcoro's reactions at the end standing amongst the bodies (and based on ani's uniform change in the upcoming preview) seems like they may take the fall for all the carnage.
