Primary sources are forensic results, business documents, phone calls, 1sthand information. Secondary sources are media, blogs, secondhand information.
Until some of the forensic results are released, everything is speculation. The only facts are as follows.
1. Zimmerman called and thought Martin was suspicious.
2. Zimmerman followed Martin and got out of his car.
3. At some point they were in close contact range and there was a physical confrontation.
4. Zimmerman had a wound on his nose and his head. That does NOT mean he was jumped or that he was hit in the back of his head - being passed as fact by some people.
5. At some point Martin was shot and killed.
6. Police arrived around 6:17 and conducted a manslaughter investigation. Zimmerman was cuffed, detained, and taken to the station. He was later released.
7. Investigation is ongoing. At this time, either there is no probable cause to arrest Zimmerman, or the DA/Police don't think they can get a conviction beyond a reasonable doubt. That could change when more facts are in.
Yes, but how those are going to be presented will make a difference.
An example...in the "facts" you presented you stated Zimmerman had a "wound" to the nose. When it's been presented his nose was 'broken'. So which is it?
So you see this whole affair is going to be spun by legal teams from both sides .....the truth more than likely will be lost somewhere in between and it will be all about which legal team "wins"....not that justice might be served...if indeed it goes to trial.
