Exactly. I'm not in LE, but I do have a job where I frequently need to get approval from a higher authority. You know the result you want, so you're only going to put things that support that result in your request (EG. they leave out that he's not in the likely age range of the suspect, which they thought they knew at this point.)
There's something of an art to it. You want both quality AND quantity. You start with your strongest arguments, like the agent does here: The murder scene is on his property, his build is consistent with the suspect, he's known to carry the type of weapons used, he lied to create an alibi, someone thought the person in the video was him, etc. Then, to pad it out and make it the evidence seem overwhelming, you add supporting facts that wouldn't really stand up to scrutiny on their own: He's physically able to navigate the terrain, his phone was in the proximity at the time, he's capable of violence under different contexts, etc. The idea is, by the time the judge (in this case) gets to that part of it, he's made up his mind in your favor, and that all just reinforces it.
