Ayoob was/is a Part-Time RESERVE police officer.
In my area Reserve Police Officers usually work at events such as football games, concerts, parades for traffic control. Some may do ride along with regular officers as back-up. In general they rarely are involved in high risk situations and making arrests.
In my old department, reserve officers performed the same duties as regular officers, and had the same training and FTO evaluations.
I saw a picture of Ayoob in uniform showing Captain bars on his collar promoting something of his. (I think it was a book.) Impressive except few people realize that Captains are administrators not street cops. In the departments my area a Reserve Captain is responsible for trying to arrange having enough officers to cover events. He/she is usually someone with a lot of spare time on their hands.
Again, our reserve sergeants, captains, etc did administer the reserves, but also worked the same minimum required hours on the street as all of the other reserves (40 hours per month)
When Ayoob did most of his writing the Internet did not exist so it was not possible to publicly disagree him as the gun rags would not publish rebuttals. Gun rags then as now purpose is to make a profit not to always publish true facts. With the Internet we now know some of his opinions are not correct.
Anyway I understand Ayoob is a member of THR so he can come defend his position.
The question remains unanswered is what court case did use of handload ammunition play a major role in the juries decision to find the defendant guilty?
(I am not talking about someone like in the movie Taxi Driver where the person made mercury tipped hollow point bullets in his workshop.)
