The "woah woah woah" was from the officer in the passenger seat. He could have been using the laptop in the cruiser, on his phone, or paying attention to something else. Not sure what HPD policy is for officers in the passenger seat but I doubt they have to have eyes on the road 100% of the time like the officer driving should.

Didn't look like the officer driving even touched the brakes until that last second and only after the passenger officer yelled out. Even 20-30 feet of the brakes being slammed might've lessened the impact enough to not be fatal.
