I will reserve judgment until more details are available.
The article indicated he was a member of the SWAT team on one of the shootings, and doesn’t say he no longer is.
Also, the article says that “at least one of the 3 officers” thought the man had a gun, but does not specifically say it was Peters.
Given those facts, it is possible that it was another cop who thought he saw a gun and Peters was ordered to shoot.
“Also, the article says that “at least one of the 3 officers” thought the man had a gun...”
Therein lies the copout. All they need do is to voice that, which indicates they felt that, and feared for their lives. Justified. What a bunch of crap. Fry em! Deep and long!
