Prosecutors on Wednesday questioned several witnesses to support their belief that George Zimmerman was acting as a “wannabe cop” who was well aware of Florida’s “Stand Your Ground” law the night he killed Trayvon Martin in February 2012. Zimmerman, 29, contests he shot the black teenager in self-defense while on the job as a neighborhood watch captain, even though 17-year-old Martin was unarmed.

Zimmerman first said he wasn’t aware of Florida State’s “Stand Your Ground” law when he had actually taken a criminal litigation course. On Wednesday, Capt. Alexis Francisco Carter testified that he taught him criminal litigation at Seminole State College, and that Zimmerman received an A in the course, according to ABC News.

When defense attorney Don West asked Carter to explain self-defense, Carter said that the initial aggressor could become a victim during a fight. "It's imminent fear, so the fact alone that there isn't an injury does not necessarily mean that the person doesn't have a reasonable apprehension of fear," Carter told the court. "The fact that there were injuries has a tendency to show or support that that was an apprehension of fear."

West then asked, "You don't have to wait until you are almost dead before you can defend yourself?" Carter swiftly said, “No, I would not advise to do that.”

Zimmerman had applied for a diploma in criminal justice in 2011 at Florida’s Seminole State College, according to records that were revealed in court, wrote. While prosecutors do not necessarily a “bad” thing that the 29-year-old was interested in being a cop, it could potentially show what his line of thinking was the night he got into the deadly altercation with Martin.

One of the accused other instructors, Scott Pleasants, said via webcam that he never covered profiling in class even though the course book addressed that subject. While Pleasants was speaking, Skype users began to flood the teacher’s testimony. Pleasants continued his testimony for the day through a speakerphone.

The Zimmerman trial is one of the hottest topics in the nation right now, and it has ignited debates about equal justice, race and the use of guns. The 29-year-old former watch captain, who is half-white and half-Hispanic, could face life in prison if convicted of second-degree murder.
