I’ve said this now until I’m almost blue in the face. There must be a legitimate threat of lethal force in order for a person, police officer or not, to respond back with lethal force. There CLEARLY was NO THREAT of any kind to Zimmerman nor any evidence of a threat. The evidence is on the 911 call and per the testimony of the victim’s girlfriend. No I don’t believe it’s problematic that a police officer has to make a judgement about whether or not a crime has been committed in order to make an arrest, last time I checked, it’s their job to to do that. How else are they supposed to decide who to arrest and who to leave alone? He murdered this young man, most likely because he didn’t like the color of his skin. If he had some other motive I have not seen any evidence of it. He was on a public side walk minding his own business, and was chased down, attacked, and shot. That is murder, there is no possible way any reasonable person could look at that situation and think it was self defense. You can’t claim self defense anywhere in this country if you chased down someone and picked a fight with them for no reason. In America, we are supposed to throw murderers in prison. The police officers and the DA in this situation need to be fired and prosecuted too. Their job is to enforce the law and they failed, miserably. This kid’s family deserves justice, changing the law does nothing if you have a police force that won’t enforce it.
