Since leaving the Police Department I have facilitated hundreds of Code Black courses teaching people initially how to effectively negotiate and escalating to passive resistance and then aggressive self defence.
There are certain things you should and shouldn't do in a street confrontation but the mind aspects can be easily remembered by Speed Aggression & Surprise (SAS) and knowing where to strike and how many times to strike.
You also need to be made aware of the legislation in your jurisdiction in relation to self defence as compared to common assault.
If you put someone down and cause them serious injury there is every chance that the cops will charge you with an offence.
So I give you this information advisedly: NEVER EVER make a statement to Police in these circumstances NO MATTER HOW FRIENDLY THE COP IS.
Typically … “I just want to clear up a few things here buddy.” Fall for that one and you will be in handcuffs before you can count to 3.
Most people who end up in prison have had the worst witness you could imagine against them … themselves! Keep your big mouth shut or you will regret it for a long, long time. Use only one word … “lawyer.”
This is worth going over again and again, and once again, every few weeks.
The one thing we need to become believers in ...is that after a violent confrontation, in addition to your being injured, in pain, mentally and physically exhausted, and scared, and possibly having pissed your pants...you will become newly afraid by the police interaction...
All this while under the effects of the adrenaline dump which will prevent you from rational thinking and or recalling anything with accuracy.
There will be a tendency to go to 'diarrhea of the mouth' MODE...you cannot control, much like you cannot control a bout of diarrhea from the other end.
I have seen much of this in my investigations of fatal incidents...like, for example, the Greyhound bus driver who, after broadsiding a car and killing the driver, told the police at the scene that while driving the bus at 25 MPH...he had first seen the car about 25 feet away coming thru an intersection...at which point in an attempt to avoid the accident, he had unbuckled his seat belt, risen from his seat, and had run to the back of the bus...at which point the collision occurred.
Go figure.
He was charged with vehicular homicide based on his statements by the police... who were chided by the judge at the 'show cause' hearing, where I had arranged for several experts to appear for the defense.
When I interviewed him and showed him the police report, he denied ever having made any such statements.
He had become a different person during the accident aftermath.
