but it’s an extremely important part of this investigation because it would disprove that the shot came from anywhere else other than that rooftop

It wouldn't prove that at all. Maybe the guy just coincidentally sneezed and that's why the pixels shifted a little bit. If he was the supposed fall guy maybe they told him when to twitch to make it look like he shot.

Having unreasonable standards goes both ways, you're using it to pretend there's some other explanation than the obvious and I can use it to dismiss any counter point you make.

Instead you should just go by your normal standards, which I think you've basically said the other evidence is sufficient to convict him on.

And exactly how easy is it to fake text messages? These are pictures of the boyfriend's phone while he's holding it and he's a corroborating witness. The easy explanation is that Tyler is a retard - and we already know he's a retard so that's a pretty compelling explanation.

But instead you believe what? Nation-state remote hacking of Tyler's phone before he was caught to covertly send those messages, or did they hack Discord? Boyfriend himself wrote both sides and then faked all the discord logs? What exactly do you think is anywhere even in competition with Tyler just being a retard?
