I don’t know whether it has been determined that Mr.Zimmerman shot Mr.Martin purposefully.
Mr.Martin may have grabbed for the gun upon seeing it and seized it by the barrel. Mr.Zimmerman, to prevent the gun’s seizure, grabbed the gun by its grip. The shooting may have been accidental.
The police, I suspect, would have fingerprinted the gun after the shooting as per procedure. If not then there is only Mr.Zimmerman’s word against the forensic evidence of a bullet wound.
I agree with you.
Mr. Zimmerman never said that he pulled the gun to shoot Mr. Martin.
He said that Mr. Martin sucker punched him in mid-sentence, jumped on him while he was on the ground, and proceeded to beat on him. He said that Trayvon then tried to take his gun, and then .... boom... Trayvon keeled over backwards, dead.
From all accounts, Mr. Zimmerman was upset over Trayvon being dead, and in the struggle I doubt whether Mr. Zimmerman knows WHO pulled/pushed the trigger.
I suspect Mr. Martin pulled on the gun barrel while it was pointed his way, or he reached for the handle and trigger, putting enough pressure on Mr. Zimmerman's fingers , squeezing down the trigger.
As has recently been made public, Mr. Zimmerman got the gun to protect himself from PIT BULLS at the ADVICE OF THE POLICE, and never had any intention of using it on humans.
