Well I guess the next time she's drunk and she's deciding whether to drive home or not, she can think to herself "Sure, whats the worst that can happen, even if they catch me I'll spend 3 days in prison and then I'll get out. Plus I'll generate a load of sympathy for myself from my fans. Ah well, what the hell, I'll just drive home drunk then...."
I don't know who is to blame, Paris, her people or the LA/American prison authorities but I really am quite disgusted by this
