The point is that this is not really about this case. This is about the process.
With the general approach of stand your ground, it doesn't matter what happened at the site. By definition, Martin was perceived as a threat. Once that happened, his death was acceptable by law with no opportunity for justice. Stand your ground means that whoever can escalate an altercation to murder first, gets away with their life and is forgiven by law.
Here is another example in Arizona. The killer is known, was never tried and walks free today simply because of stand your ground:
About 7:30 p.m., a 22-year-old man and his girlfriend ordered food at the Taco Bell drive-thru and were told to pull up while their order was prepared.
At the same time, 29-year-old Daniel Adkins stepped around a corner into the path of the vehicle and angry words were exchanged between he and the driver.
They got into an altercation and Adkins was shot once by the driver. He died at the scene. The driver, a 22-year-old black male, called police.
At first, the couple claimed that Adkins had a metal pipe that he swung at them — but it turns out he was holding a dog leash with his yellow lab on the other end. The dog, Lady, stayed by Adkins’ side until the Humane Society came. Adkins lived with his mom and dad. He’s 29, but his family says he’s mentally disabled and has the mental capacity of a 12-year-old. He didn’t drive, and walked wherever he went. A metal pipe or bat was never located. An independent witness did say Adkins swung his fists in the driver’s direction.
“He swung his fist towards the driver window, and at some point the driver shot him,” says Phoenix Police Sgt. Tommy Thompson. Police did not arrest the suspect due to Stand Your Ground laws.
