The "no ban at the time" Chinese semi-auto he used. He also had a Taurus PT-92 - same as mine that I purchased in March 1989. I had no idea at the time I'd bought what he used.
My 1988-1989 era Taurus. It was my first handgun.
Pretty good article on the event. If there is a cool part to the story it is that one of the boys who were shot survived and grew up to become a pro-gun police officer.

To me nothing is better than taking the steam out of a anti-gun leftist than live testimony from a person who survived a shooting event and chose to become pro-gun after. I am one of those.
