Another concern is the absence of a timestamp. This I'm not as worried about because they probably cropped it out. It's definitely understandable, especially for public-facing video to crop out some of more sensitive metadata like time, officer info, car info, etc. It's not nearly as concerning as the video itself.
Then there is the case of the actual jumps themselves. What makes me doubt is that they aren't just jump cuts, there's some stutter and back and forth motion for each cut, and there's also some video artifacts for each one.
I despise the police, I really do. The very idea of police is repulsive and disturbing, in my opinion. That being said, I think LA Times is definitely suspect here for such a bait-y headline over what looks to be an actual video issue. I mean: "arrest video has continuit problems, anomalies"? No shit, the video is messed up. It also has the entire dialogue between the two leading up to the arrest, it even has a whole other stop from another time!
I just don't see the possibility that they are hiding something, when there is so much on tape already.
