I totally thought the shooter in the car on the left was an undercover which is why he was ignored. That was a near fatal error not checking the car before trying to conduct the raid.
That's what I thought as well. Just about every SWAT "bust" video I have ever seen on TV the officers visually clear all vehicles on or right near the suspects property. They turned their back on the car without clearing it and the price was a wounded officer. Hopefully LEO's everywhere learn from this and reinforce the importance of clearing vehicles before turning your backs on them.
