And where do you think he got that description? The cop wasn’t there in the store and didn’t see anything happen. His only information to make the “berserk” claim was what he had been told by the Costco clerk on the 911 call.
I don't know, where did he get the information? He didn't attribute the description to the store employee did he? You don't suppose that the fact that several of his men blew an innocent man away may have caused his creative juices to flow and for that description to come out?
