It's "aviator" if you please. Don't know how this weighs in but one of the many comments I've seen;
As a 37 year LE veteran who served numerous search and arrest warrants, including high risk warrants, standard protocol is to stand or crouch to the side of a door when knocking and announcing a warrant. Or, wait for the suspect to exit (an apartment in this case) if the suspect is believed to be armed and dangerous.
I hate to say it, but 5 Agents bunched at the front door of an apartment was tragic tactical execution, IF that is what happened (IF all the shots were fired through the closed apartment door).
