I appreciate your comment. I still would not say that Zim “killed” the man.
Semantics is the universe of the Justice system.
By way of example, one of the Commandments is “thou shalt not steal”.
Therefore, if I am accused of stealing and am acquitted in trial, am I still a “stealer”. Was I ever a “stealer”?
NO.
It works the same way with “thou shalt not kill”.
Again, IANAL. But I could play one on TV, if anyone wants to offer.
No, your analogy is incorrect.
There fact of your having stolen was not established by confession and that was the question to be determined at trial, but there Zimmerman has confessed that Trayvon died from Zimmerman’s actions and that fact is not in question.
Therefor he is a “killer”, whether he is convicted of murder or not. “Alleged” is an adjective that only applies to facts that have not been established.
I believe it's originally "thou shalt not commit murder".
