I fully believe the "almost eight minutes" number originally going around was intentionally disseminated to make the murder seem not quite as terrible.

"Sure, it looks bad, but before we judge this blue hero for using a tactical compliance technique for slightly longer than department policy dictates you have to take into account the totality if the situation, wait for the edited police camera footage, hear from the information officer, and pull the suspect's high school transcripts.

I mean it's not like they did something crazy like choke him out for 10 minutes or something, you know?"
