Don't apologize to the perpetrators. Don't set them free. Don't blame it on a video. Don't call it workplace violence. Don't "investigate" until after the next election then quietly release the results at 4:59 on a Friday afternoon. Don't tell us you did everything you could when you didn't lift a finger. Don't say "it's a priority" that you're going to focus on "like a laser" while you twiddle your thumbs. Don't pass the buck.
You've done every one of these things before.
DO waterboard the cockroach until he tells you where the rest of the scumsuckers are. It worked with bin Laden's courier, and it will work with these guys.
