Lindsay Lohan has been behind bars plenty of times for DUIs, probation violations and other legal infractions, and now the starlet has taken to Twitter to ask why fellow actress Amanda Bynes hasn't been hit with the same penalties.

In April Bynes was arrested for a DUI, and since then she's had two hit-and-run accidents, a citation for driving with a suspended license and last week she was photographed smoking what appears to be marijuana inside her car. Yikes!

On Sunday, authorities impounded Bynes' black BMW, but Lohan still wasn't happy, as she tweeted yesterday evening, "Why did I get put in jail and a nickelodeon star has had NO punishment(s) so far? ... These are the moments that I appreciate my life experiences, living without regrets and Disney for supporting me as an actress."

Bynes has yet to comment on the matter...
