You could still be brought before a jury to determine if you knowingly provided the wrong PIN (and thus knowingly gave false testimony) or not. Records of you intentionally setting two very similar PINs and discussing any such plan could be used to convince a jury that it was malicious.
> You're going to have a hard time convincing the judge that you "accidentally" gave the wrong pin in this case
Counter-example: muscle memory.
My OH has - more than once - attempted to tell me her PIN code. On more than one occasion two of the digits have been transposed. Happily I know that it's the middle two digets that get transposed... :)
yes, and it would be up to the jury/court to judge if you made a mistake or if you intended to give the wipe pin. Not different from you shooting someone saying you thought the gun was a fake gun. They will evaluate and decide if they believe you are lying or telling the truth.
