Is George Zimmerman a "loose cannon"?
Most ordinary human beings would be relieved to be acquitted of a manslaughter charge.
This feeling of relief would be followed by a resolve to avoid culpable wrong doing.
But not Mr. George Zimmerman!
July 13: Acquitted of second degree murder / manslaughter.
July 18: Helped rescue a family in overturned vehicle.
July 28: Pulled over for speeding in Texas. Warned.
Sep 04: Pulled over for speeding in Florida. Given ticket.
My opinion is that Mr. Zimmerman has a very high opinion of himself; to the extent that he can operate outside of, or above, the law.
Unless he has a genuine change of attitude, I make bold to say that he will get into serious trouble.
