Clint Emerson and Pat MacNamara On 'Tactical Deception'

 Two things of note. First, the issue of creating space was something I originally learned from Carl Cestari.  Second, the Police Interview position is essentially identical to 'The Fence' position popularized by Geoff Thompson in the UK.  I originally saw a very good description of it in a video called "Practical Hand-To-Hand Combat for the Police Officer"  from Chris Caracci, a former member of SEAL Team 6.

All of which goes to show that while certain methods/techniques can have different names, when you come right down to it, where personal protection is involved, your best results will most likely come from a small handful of basic skills.
