Just like when a dad tells his daughter not to go on a date with Jimmy because he's trouble. The daughter sneaks out of the house to meet up with Jimmy. Clearly she's forfeited her right to say no or to resist his advances...judging by your stellar logic.
That's a vastly different situation there, and you know it. But you wanna go down that road, great. Lets go.
Little Ms. Zimmerman wants to get some action. She hasn't had any since she contracted HIV from her previous boyfriend. So she puts on her tightest, littlest outfit. Even "forgets" her panties, and goes to the party, even after told this is a bad idea. Ok, no harm no foul. She see's Mr Martin at the same party; one he shouldn't be at either. She goes over to him, and nothing really happens. A little necking, but everything's well under control. Great. We're fine at this point.
But then Mr Martin then walks away, in to the restroom we'll say, she follows him. Mr Martin did not ask her to do that, she was told not to by her father, but Ms Zimmerman has jungle fever and just can't stop. She was not asked to follow Mr Martin into the bathroom, nor invited, but she did anyway knowing what could happen. And it did. And now Mr Martin has died of AIDS.
The evidence contradicts the testimony of people in both camps, so we can't really believe either of them. All we know is that Zimmerman purposely put himself in a situation he knew was dangerous and against the advice of the police department(if you go back to Neighborhood watch guidelines) knowing that if it came down to it, he had lethal force on his side. He did not identify himself as neighborhood watch, he did not say he was there in mind of the safety of the neighborhood. He relied on his gun to get him the final and only word.
To be honest, the fact that he's waived his right to the "Stand your ground" rule is probably the best thing he could have done, since what he was doing could be construed as vigilante justice, which is against the law.
If threatened with life or limb a person has the right to defend himself with lethal force. (can we agree?)
Well sure! But the problem here was he put himself in a position where he knew he could need to use it. He didn't have to be, he was advised against it, and regulations state you should not put yourself in that position, but he went in anyway.
What's the safest way to not get your valuables stolen at the gym? Bring a lock?
Heck no. Don't bring your valuables to the gym.
