A prosecutor, a jury, and a judge, will all have a chance to decide that you're telling the truth. There is not mathematical proof here (there never is in any trials, really), so it will all come down to: do we believe the LEO's and the defendant's experts' testimony? Recall, the defendant won't testify -- their lawyer won't let them -- but if they did, they'd probably do themselves in anyways, the court (jury, judge) won't believe them. There is no plausible deniability here, really.
