This absolutely helps Zimmerman. The state has to prove guilt beyond a reasonable doubt. It would seem there are no reasonable witnesses and the defense will be able to easily impeach any and all of these witnesses who are demmed hostile to Zimmerman.
“A young mother in the townhome community first said she saw two men on the ground but wasnt sure who was on top; she later said Zimmerman was on top because she recognized his size based on news reports.”-—
But all the news reports grossly misled the public about the respective sizes of GZ and TM. At the time of the incident, both weighted about the same and TM was nearly 6” taller than GZ!!!
