That alleged screen-cap smells. It’s dated January 6th: more than a month and a half prior to the killing. Yet, he wouldn’t have been in Sanford at that time, he would have been at home in Miami. He was in a 5-day suspension when he was in Sanford. Assuming it was the last night he would be staying in Sanford, he couldn’t have arrived prior to Feb 21st: still a month and 15 days between the alleged tweet and Trayvon’s arrival in Sanford....

I am not attempting to either confirm or deny validity of the screen captures.
The following is simply a fact:
Tracy Martin has stated that his son had visited in Sanford previous to February 26.
