“I saw the first three of our guys fall, and we started running,” said their brother in arms, another Cossack, who said he was there May 17”
No where in the article does it say who shot those three guys. The Washington Post tries to imply but cannot make a direct link. The question still remains as to who shot who.
“No where in the article does it say who shot those three guys.”
Well, if you actually read the whole article the witness explicitly states a Bandidos member fired the first shot, a fatal shot to the head:
“Trouble started almost immediately, he said: One of the Bandidos, wearing a patch that identified him as a chapter president, ran his bike into a Cossack standing in the parking lot. The Cossack who was hit was a “prospect,” a man in his mid-20s who was “striving to become” a full member of the club.
“They came up really fast, and the prospect turned and faced the bikes,” the Cossack chapter president said. “He fell backward into other [parked] bikes. The guy who hit him stopped and got off of his bike and said, ‘What are you doing? Get .... out of my way. We’re trying to park.’”
Cossacks quickly jumped to the prospect’s defense, he said: “Guys were saying, ‘You’re disrespecting us,’ or, ‘We’re not backing down.’”
In a blink, it started, he said: “Two punches: One from them, one from us.”
A Bandido with a patch identifying him as sergeant-at-arms of the same chapter threw a punch at Richard Matthew Jordan II, 31, known as “Richie,” who was from Pasadena, Tex. Jordan punched the guy back.
“At that point in time, the sergeant in arms shot Richie point-blank,” the Cossack said.
Police said Jordan died of a gunshot wound to the head.”
