Being a vigilante has consequences that should have been foreseeable.
Please define and provide evidence he was a vigilante.
The dispatcher certainly saw this happening and ordered him to stop his unwise pursuit.
No. Dispatcher actually testified they can not give orders, only recommendations. Even if he had ordered Zimmerman to stop, it was not binding on Z. Secondly, Zimmerman did stop following Martin. This is supported by Zimmermans statement, the dispatchers testimony, and the testimony of the girl on the phone with Martin.
Again, we disagree because we are talking about the actual event, while you appear to be discussing a fictional scenario.
Carrying a weapon come with added responsibility.
GZ was negligent in those responsibilities
Please provide evidence of where/how exactly he was negligent? His conduct was in compliance with laws and regulations for a CCW holder (unless you have evidence he drew the weapon prior to being in fear of imminent serious bodily harm)
and now an innocent 17 year old is dead.
Again, I have a problem with defining someone violently assaulting another as innocent. Do you have evidence that was not presented to the jury that this did not occur?
How could this be anything other than manslaughter? (Yes, I already know, the jury did not think so.)
Because a person has a legal right to use lethal force to counter an imminent threat of seriouly bodily injury (serious as defined by legal statute)
Worship God, not guns!
