In some of the animated shows I've watched there's a thing where a character will be proven to have done a crime. Then the police slap handcuffs on and it's implied (and sometimes shown) it's away to prison. Which isn't how it works or how it shouldn't work.
But in the cases I'm thinking of, it's shown clearly that the culprit is guilty so the idea of a legal proof feels supercilious; we know the character has committed a crime; we've seen evidence; the character may even be described as confessing ("I would have gotten away with it").
All this is to say: would any and how much of the evidence presented by the gang be applicable in a legal conviction?
The gang's goal in solving mysteries is more to solve what this weird thing is — which includes how the uncanny thing is done, followed by who and why.
Someone like the Creeper could be convicted, as the whole plot is him trying to get back incriminating evidence. A lot of the music's plots might have merit due to multiple witnesses. But something like Cutler, how does that work if he's been declared dead? And what about Buck Masters who was kidnapping dogs; is he going to prison or just community service like Marcy?
Which reminds me that WNSD was a lot more flexible about what the actual outcome of the mystery reveal. Culprits we're not immediately carted away to prison, which is retrospectively maybe unique for any series which included the "rubber mask" culprit".
