I had two CCW classes from different instructors (first one mandatory for the license and the second one mandatory for the renewal) and in both classes one of the primary focus of the class was the legal aspect every single person who ever has to use their firearm in self defense is going to have to face.
And in both classes the instructors emphasized the importance of never, ever willingly answer any questions on scene after an occurance. The only response you should ever give is that you refuse to answer any questions until you have consulted with your attorney.
This is for your protection because no matter how innocent you may be in whatever has occured, you just might have a local prosecuting attorney such as Mike Nifong.........
My experience is similar.
There was even discussion regarding whether to say something like, "I shot him because I feared for my life".
There is no obligation on the part of an investigator to believe such a statement. So any notion that making such a statement will eliminate arrest, transporting, booking and bail is not really justified.
If the circumstances don't themselves argue that a shooting was justified, the statements of the shooter isn't going to change that.
My decision is to say nothing. I have also explained to my wife that she can't be compelled to testify against me and therefor she should say nothing as well.
If the authorities can't even determine whether it was my wife or me who fired a shot, it in no way denies them their ability to prosecute a crime. Since I have a right to remain silent, I intend to use it.
