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...

brer rabbit: "no brer fox dont throw me in the briar patch!"

suspect: "no you cant force me to put my pinky there", attempts to make pinky inaccessible.

other: "we will charge you with obstruction if you resist placing the pinky"
