The perp was hit three times not seven.
Also from the article:
“The police commissioner said the suspect pulled his gun out of his briefcase as the officers approached, pointing at them. “
Doesn’t sound like “an Aurora-style killing.” In fact it was a premeditated homicide where the perp killed his intended victim and was walking away. It was the police who turned it into Aurora redux.
He came around the corner, chased by two construction workers, turned around and pulled his gun on the police. I’m sure, if it had not jammed, he would have killed as many people as he could have. He was angry and he was trying to do suicide by cop (and later reports have said that he was hit seven times).
You sound like you’re in the “but why couldn’t they shoot the gun out of his hand” crowd.
Whenever there’s firing in a crowd, people other than the intended victim are going to get hurt. Guns aren’t magic.
