In the 911 call, Zimmerman said something like “it looks like there’s something wrong with him, like he’s on drugs or something” (I’m writing this from memory, so I probably got that quote slightly wrong).
The Zimmerman-haters assume that Zimmerman is just too racist to know the difference between a sweet 12-year-old kid like we see in the photos and a suspicious person on drugs.
However, now that the real evidence has come out, we saw a video from the 7-11 in which Martin stumbles around in a weird zig-zag pattern, indeed like he’s on drugs. And then there’s a cigarette lighter on his person, and there was THC in his blood which means he smoked a joint during the previous 24-hour period.
No, marijuana does not necessarily make Martin more violent, but there are plenty of arrests of people who commit violent crimes while on marijuana, so there’s lots of evidence that smoking a joint doesn’t make violent people too mellow to commit violent crimes.
Martin’s drug use goes to both Zimmerman’s motive for calling 911, and Martin’s motive for running away. For all we know, Martin had a bag of joints on him, and he ran away to hide them somewhere (a more likely scenario than Martin being scared to death of Zimmerman). And no, Martin doesn’t deserve to be shot for smoking a joint, but that’s not why Zimmerman shot him. Zimmerman shot him because he was getting beaten up.
And as to whether Martin was just minding his own business, the homeowners association has a legitimate interest in not letting people smoke drugs in their community. Smoking marijuana is against the law in Florida, isn’t it? In fact, possession of 20 grams or less is a misdemeanor punishable by up to a year in prison, and I understand that this crime is heavily prosecuted in Florida.
