Perhaps a lawyer can chime in here.

My impression is deliberately doing this would be illegal. It would have to be convincingly deniable somehow.

Is there a way to do that?

There are very specific rules for proving destruction of evidence. For a criminal case the burden proof in the US at least is "beyond a reasonable doubt", so someone would likely have to prove that you knowingly destroyed valuable evidence before you'd get in big trouble. And if you haven't already been served with something saying you need to preserve evidence, they might not have any claim to information they had no idea existed beforehand, especially if you don't talk.

Believe this is bad legal advice. They would only need to prove you destroyed information with intent to impede an investigation/case. They would not need to prove something convicting or weighing was destroyed.

if something made them decide to force a particular finger into a sensor, what happens next is a result of thier own actions.

Maybe, maybe not. I'm sure there's some legal mechanism for punishing you for setting a boobytrap.

You'd also have to rely on this unnamed other to force that particular finger, rather than the others...
