zimmerman's dna found under his fingernails. the defense did spend time raising some questions about the number of varied ways that dna samples could be degraded. also, again, as you indicated, they started with a win for the state, the state had been arguing to get this evidence, to get this evidence in, that george zimmerman did know a little bit more than he let on about the law. also that he wanted to be a cop. we heard from someone from the prince william county sheriff's department in virginia who said that, you know, zimmerman applied several years ago to be a cop. that application was rejected because zimmerman had basically a poor credit history. we also heard from captain alexis carter who taught a criminal litigation course to zimmerman. said that zimmerman was an "a" student in that course and also said in the course they covered stand your ground, you'll remember, of course, the fox interview that was played for the jury yesterday.
