It could help Zimmerman out a lot and he needs it. He is the second dumbest guy in Florida right now (I'll post the first). He lied to a judge about his assets for bail. Not a big deal under normal circumstances, but given that his whole defence is the he's a decent law abiding guy who was afraid for his life, WTF was he thinking lying under oath? He has to take the stand as its his whole defense. And the prosecuter can say "Ladies and gentlemen of the jury, he lied under oath to this court once to get out of jail, what makes you think he isn't doing it now"? If Trayvon was drugged out its a godsend to Zimmerman (who still should have stayed in the damn truck).
