My bolding. We should absolutely 110% not trust this as fact. We've seen the police come to unlikely conclusions on the basis of this type of "observation" before. I know the Cooper case better, so some examples from that one include "It smelled like Downey", "I saw some hay", "The bed didn't look slept in", etc. We should not trust "as fact" police observations. They seem to recall things that are convenient to the narrative that they are pursuing at the time.
Again, that is the difference between testimony evidence and fact. You can use it as contributing to determining what is fact, but an officer's statement or sworn testimony is not fact. It is evidence.
