Here’s the deal: They might have had probable cause to arrest but did they have evidence beyond a reasonable doubt of Zimmerman’s guilt? It is very common for police to wait until the investigation is complete before making any arrests. There were still some things they didn’t know that night.
Indications are that the police did not identify Trayvon until the next morning. Without his identity they had no way to check for a criminal record. Toxicology reports won’t be available for a few days either. What if the police arrested Zimmerman and then discovered that Trayvon was a known gang-member who was high on cocaine when he was killed?
Actually, the toxicology report may be the only interesting thing to come out of the autopsy. We know he was shot and who shot him. The CPR attempt would have really messed-up any forensic evidence on the skin and clothing. If the toxicology report shows drugs or alcohol in Trayvon’s system that will help Zimmerman.
If I was the defense investigator I would want to know a lot more about Trayvon. Where was he staying? When did he leave the house? Where did he go? Is the place he was killed between those two points? I once won a case where a girl said my client and another boy tried to rape her on the way home from school. One problem with her story was that the place she said it happened was the opposite direction from her home. That’s why you check these things out.
The media says he walked to 7-11 to buy an iced tea and some skittles. According to Google the nearest 7-11 is almost two miles away and it was dark and raining. My kids wouldn’t walk next door on a rainy night, but then I’m from California. What time did he arrive at 7-11? There should be a register receipt showing a purchase of an iced tea and Skittles with a time and date stamped on it.
Read the whole thing. Life isn’t like CSI, and despite what our opponents have been saying, there’s not much that’s remarkable about this case in terms of the law.
