Why would he want to get out of a jail potentially dangerous to his life - courtesy of media people’s and racebaiters’ smears - and staffed by people among whom are some of the people trying to railroad him? I dunno … beats me.
If Zimmerman lied about how much $$ was in that legal defense fund rather than not knowing at the time of his testimony how much $$ was in it, it was wrong. But your question is an argument from silence, and arguments from silence are vulnerable to alternative answers. My first sentence gives two alternative answers to your argument from silence.
Since we’re asking each other questions … why did ABC News need use that low quality video to claim Zimmerman was lying about having been injured that night? Better quality pix were available … but they proved Zimmerman told the truth. Why did NBC people edit the 9-1-1 tape to make it sound like Zimmerman made a point of Trayvon Martin’s race when in fact Zimmerman only mentioned it in response to the operator’s direct question? Why did intial MSM reports claim Zimmerman was white, when in fact he is mostly Hispanic, with at least one black ancestor, has numerous family friends who are black, etc.? Why did the MSM - falsely, as it turned out - make a point of Zimmerman’s race? It’s not like Zimmerman was then yet uncaptured. There’s a rather long thread on RO about the case, and it has other examples of how Zimmerman has been smeared. These questions are just from memory.
Guilty people don’t need to be smeared, lied about and railroaded.
