And you said you are a lawyer? (Or work in a law office or something?)
Tell me which type of evidence, Physical Evidence no less, is non-refutable?
I mean, you don't like that and you don't want to count them, sure, every lawyer does that, that's what motion to suppress is for, but then that does not mean that evidence have no evidentiary value, but to tell me first "Perception is common knowledge" and then you tell me because of this "Common Knowledge" which is a perception which is NOT any kind of knowledge or even fact at all, is obfuscating fact with "wrong" evidence.
Dude, I was going to say don't quit your day job, but then you tell me you work in legal field. So............I am torn
