No one is liable till proven guilty  but you will be implicated .. and the burden of proof shifts to you that you didn't give your car as an accomplice  .. that is the reason you must file a stolen report as soon as you realize you car (or another asset ) is stolen ...  

 There is never a burden to prove innocence. There is the state's burden to prove guilty beyond reasonable doubt.
