Not only did she need to be instructed to stop lying during her deposition, but she made no effort to contact anyone, let alone authorities who could help him, when she supposedly heard Trayvon in distress being attacked by a big spooky old white man.
No call to Sanford police... no call to Miami Gardens police... Trayvon's family didn't know about her hearing anything for weeks, and she avoided and refused to talk to police for quite some time. When she finally spoke it was in a very controlled interview with Benjamin Crump, who is a slimeball if there ever was one, and no questions from the reporter on the other end of the phone line (who was a hack in Crump's pocket anyway) were allowed.
She had to be prompted repeatedly before she came up with the "I heard a little 'get off me'" which she made no mention of during the first 4 or 5 recitations of what she heard before the phone went dead, and even after coming up with this she told BDLR that she couldn't know for sure who she heard saying it (which has conveniently been ignored, partially because she has the same command of the English language you'd expect from a retarded dead possum fetus.)
She is worthless as a witness. What she says all matches GZ pretty well anyway, Trayvon spoke first (confronted GZ), said he wasn't going to run, she says things which could indicate he was at his dad's gf's place then turned around, though again her ability to speak English makes some of this difficult to be sure on... and the faint, distant "get off me" she heard, if she heard it at all would much more logically have been GZ. Who had someone on him? GZ. Who had the injuries? GZ.
Her "boyfriend" was a delinquent, violent, hotheaded, drug abusing thug who got exactly what he deserved. And society deserves to not have anyone like him in it.
In all likelihood the reason she didn't contact anyone is that Trayvon articulated exactly what he planned to do before hanging up with her, which was to go beat that cracker's ass. Her guilt she wouldn't explain in her deposition is most likely born out of encouraging him to do exactly that.
You're not going to call cops if you know your friend was breaking the law, you might inadvertently give them his name when they didn't have it before, if they were still trying to catch him, or you might end up incriminating him and saying something contrary to what he's telling them if the's in handcuffs for assault down at the station.
If you know he was the aggressor and was assaulting the person who shot him, later on, you're going to do exactly what she did. You're going to stay under the radar and avoid talking to cops because you had a role in it by encouraging the assault, and you know information which puts Trayvon in a worse light and could end up helping the person who shot him, which in your stupid worldview wasn't justified just because Tray-tray was beating his ass. Plus he's not black, so the idea of siding with him over a black person, let alone your friend, is unthinkable.
Later when Crump gets in touch with you and coaches you, now finally you can talk to authorities.
It stinks to high heaven.
