Paris supermarket SWAT entry

I'm not an expert in dynamic entry, but when you've got a stack of 100 guys in full kit and only one makes it through the door, things probably didn't go as planned.

From someone who is more of an expert - Travis Haley:

Come on guys... Damn... I mean good job getting the goons but watch the Blue on Blue... (when bad guy comes running out the door) not to mention the 1 man entry with 100man stack behind him...

A messy looking entry like this isn't uncommon. The lead guy(s) go in, bullets start flying and confusion, emotion take over and the rest of the stack ducks for the nearest cover.
