Actually, a FReeper had the most plausible explanation for the entire thing.
Trayvon is casing houses (on his way back from getting Iced Tea and Skittles...which are completely irrelevant to anything, but the media seems to disagree with me....). Zimmerman sees him. Trayvon sees Zimmerman, or hears him talking to 911 on his cell phone, and stashes his tools as soon as they're out of sight from each other.
Zimmerman heads back to his car. Trayvon doubles back to get his stuff. Inadvertently runs into Zimmerman, they have a few words, and the rest is history.
I like all of the speculation about Trayvon "lying in wait to ambush Zimmerman" and so forth. But the above explanation is simple and sensible, and Occam's razor says it's likely correct.
Thanks for your reply. Trying to keep up with the true facts of the case and totally missed this.
They do it to express his supposed innocence, but I've learned there is a street concoction of Skittles, watermelon ice tea and cough syrup that supposed to get you high. It's called Purple Drank, I think.
The coroner's report mentioned that not only was there pot in Trayvon's system, but his liver was already starting to be damaged by the Purple Drank stuff, so the media is either laughing in our faces or showing thier ignorance.
