I just ran the numbers from the video. Giving the "investigators" the benefit of the doubt [3/8 inch=20 feet, instead of 1/2 inch-20 feet, we get 34 vehicle lengths [20 feet] from the time the truck's brake lights come on in the video. That's 680 feet, not 862 feet [the difference is most of a football field]. The "investigators" neglected to take into account that Finicum crossed lanes when coming into the blind curve before the deadly [and probably illegal] hidden roadblock- a common occurrence during regular driving on twisty roads.
Did it myself tonight, several times.
I think it's noble that the leos hired the "intellectually challenged" as "investigators" in this case.
Good on them, and more power to the ADA. :)
I realize that your internet video forensic skills are epic, but you do know that it's possible for investigators to actually visit the location in question, right?
