They wounded a security guard, but were fortunately dispatched by a police officer working security.
A vehicle right behind the bad guys, travelling with them, took off.
It was stopped by police.
It was driven by an undercover fbi agent, who had been communicating with the terrorists and egging them on.
My guess, his job was to observe the slaughter.
Ohhhh. I didn’t know about the fbi car. Thanks.
