This gets me as well - racially profiling TM wouldn't mean that GZ is guilty.
According to most "Racial profiling" in this case basically means that based on his previous experiences Mr. Zimmerman reasonably suspected that TM was engaging in suspicious behavior. Does that suspicion mean that GZ wasn't allowed to defend himself?
This trial is an attempt by the establishment to placate a certain segment of the population who are predisposed towards committing acts of violence and thievery against other people and businesses.
This segment of the population has been egged on by an irresponsible press, irresponsible politicians, and irresponsible public officials up to and including our irresponsible president. These people were manipulated for the purpose of advancing a specific agenda.
Once the wrecking ball started rolling... the damage was inevitable. No matter what the outcome we are all going to pay a price. The damage has already been done... we just don't know yet whether in the end what proportion it will be in the form of murdered and injured innocent people and stolen goods or the wreckage of the reputation of what is left of our legal system.
