I don't think the crime of destroying evidence / tampering with evidence depends on what your status in custody is. If the police knock on your front door and you start shredding documents, that's still a crime.
Now, could that get tossed about because they denied him access to a lawyer? Maybe, I don't know about that part.
What if I have a camera/microphone near my front door, that when law enforcement is detected, it auto wipes my data, with no interaction from me?

Isn’t the relevant bit whether you think you’re doing crimes and/or being investigated?
If I’m shredding while the cops knock on my door because they’re looking for a missing cat, that’s obviously not criminal. (I guess the more-pertinent comparison would be they knock on my door and then I put stuff in the shredder while I check around my home.)
