Posted by parisite: As I've said here in the past, a justified shooting is a justified shooting, no matter the ammunition.
Regardless of whether you or someone else has said it before, that is a true statement. It is unimpeachable.
The problem arises when it comes to establishing after the fact whether a shooting was justified. Without a sound and video record from beginning to end, with multiple perspectives, that can be difficult to address, and subject to great uncertainty.
Gunshot residue (GSR) evidence is routinely used in shooting investigations.
On
some occasions, it
may be important to the defender as a defend
ant to introduce GSR pattern test evidence from exemplar ammunition of the type used in a shooting. Such evidence may be critical to countering other forensic evidence and/or unfavorable eyewitness testimony.
The applicable rules of evidence, whether derived from Frye v. US or Dow v. Merrell Dow or something else, depending upon the jurisdiction, and within jurisdictions, possibly depending upon whether the question relates to criminal culpability or civil liability, will mitigate very strongly against the introduction of such evidence if the ammunition used had not been assembled by a third party under controlled conditions, and the assembly records kept under independently controlled custody. That is something that some, but not all, experts understand. I have been trained in that field.
Many people do not understand that, and still others seem to refuse to accept it. Let us hope that they never learn it the hard way.
I understand the advantages of hand loaded ammunition. Given a choice, however, I will not carry it for self defense. It is a very simple matter of objective risk management.
