Reloads for defense are truly a bad idea. It opens a legal can of worms that an opposing lawyers of prosecuters will use against you. Then there is the recreation of court of the exact ammo that will be needed in testing for court evidence. Batches of like commerecial ammo can be obtained by the defense and with a similar or same gun, can have test done that show the ballistic evidence for you is real and viable. With home brewed stuff, it cannot be replicated in that same form, or way, and allowed in as evidence. Even if the recipe is the same. That is the way it works.Commercial ammo is made the same way and with the same batch consistency can be shown. Since questions can be raised about the how,when, or no way to know if each box of handloaded ammo is the same ( even if documented human fallibility will be introduced as you could have made mistakes), then the prosecution can and will hang the accused out to dry.
Why one does not use reloads for defense.
As for Mas Ayoobs record:
28 + years as a police officer. Still an active officer. 30th year as an accredited deadly force instructor.
15 years as a chair of the firearms committee for the American Society of Law Enforcement Trainers, 11 years as a senior research associate for the Center of Advancement of Applied Ethics at Carnigie-Mellon University, 14 years as a police department prosecutor, two years as co-chair of the forensic evidence committee of the National Association of Criminal Defense Lawyers. MOre than a decade as a trustee of the Second Amendment Foundation,1995 won the first National Tactical Advocate award,1998 was OUtstanding Handgunner of the Year,won the Roy Rodgers Award for advocacy of responsible firearm use, James Madison award for the advocacy of Second Amendment rights for private citizens, 7 books written on deadly force,it's use, and ramifications, the law ans how it pertains to shootings.
That's his credentials.
One has to know the law and hold the high college degrees to do what he does. also has to know the law forwards and backwards. It's been and is his job.
The trial lawyer's association printed above,sends out teams across the country to educate attorney generals,defense lawyers,police departments, civilians,judges, and other involved people. Mas Ayoob is part of the teams that go out and do this. He reports in tactical and police journals all the info given him by the lawyers and the justice system in general. Even give examples of cases and the ones that are setting precedent for further court cases at all court levels.
So I figure with that kind of background,experience, and resources in the know, he must know something. His writings are backed up with the facts as they are known.
