So Alex is misrepresenting this case that he's covering to make it appear that the system is now just out to protect criminals and punish the good people, which is code for white Christians.

The prosecution successfully argued that the shooting was not an act of self-defense, but that Martin had laid in wait and shot these intruders without first giving a warning. This wasn't the sort of case that Alex is portraying it to be, where the burglar is hurt by someone practicing legitimate self-defense and then sues the homeowner for it. It's a clearly unhinged lunatic with a history of shooting at people with a clearly racist past, using deadly force against intruders to his home who had not presented a mortal danger to him.
