Way back when, when the BOP actually taught (effective) self defense, they taught a limited series of Aikido techniques. The most (in)famous involved the mantra of "step back and cross-grab". It was actually a great technique, but was taught with a chuckle:

"Step back and cross- (grab a mop wringer!)"
"Step back and cross- (grab a fire extinguisher!)"

That jailer works unarmed, but knows that anything can be a weapon. Grab a phone, stapler, fire extinguisher, mop wringer, office chair... use anything you can lay your hands on.
