The problem for the police is that under FL's Stand Your Ground law, they would have the burden of proof of showing Zimmerman's actions were NOT self defense.
The media is going out of their way to fan the flames by showing photos of Martin from when he seems to be about 13, rather than more recent photos like this one:
Granted, the media’s handling of this is horrible. I will say this though. If I saw that kid walking down the street, it wouldn’t scare me as much as a grown man chasing after me on the same street. He is a kid who committed no crime.
Wearing a hoodie indoors, yeah that makes a lot of sense. /s
You should NB that the photo you’ve posted has been altered.
Look at the jaw line on the lower right (subjects left jawline). Look at the black background behind it. See how the line is crisp and has a very high contrast vs. the black background? It’s been altered, without doubt.
See how uniform the facial grey tone is? Again, this is evidence of alteration.
