Jay Leno covered that in his monologue tonight.
(I paraphrase)
"George Zimmerman was pulled over for speeding by police in Texas. Zimmerman told the officer there was a gun in his car (which is legal in Texas), but the officer let him go with just a warning.
After all, there was no reason to hold him, there is nothing illegal about going down the street minding your own business."
You still have time to catch it when "The Tonight Show" runs on the W Coast."
