I don't have the skills to post a proper diagram, but if I did I'd make a decision tree out of these:
#1. Do you believe the police version of events?
The first version they offered was a pack of lies that included things like Tamir sitting at a picnic table with others, the gun being on the table, the cops slowly approaching him, etc. The second version only came about when the video was made public and includes disputed claims regarding Loehmann's actions in the 1.5 seconds between his arriving on scene and shooting Rice.
If you don't believe the police version, then you won't believe anything based on it such as the statement issued by the Prosecutor's office. If you do believe one of the police versions, then :
#2. Do you believe the police shouted orders to Rice as they pulled up, that Rice understood he was the one being shouted at, and Rice could make out the words?
Witnesses to the events did not hear Loehmann or Garmback say anything. If they were shouting from inside the car as they drove up, how would Rice have known they were shouting at him, much less what they were shouting? In the mere 1.5 seconds before Loehmann opened fire there was little chance for clearing up any misunderstandings. So do you believe there was actual communication between the police and Rice before Rice was shot?
If you don't believe Garmback and Loehmann communicated with Rice, then there was no failure to comply with their orders. Rice isn't responsible for their failure to communicate. If you do think Garmback and Loehmann communicated with Rice as the cruiser came roaring up to him, then:
#3. Assuming Loehmann or Garmback ordered Rice to drop his weapon and Rice heard and understood him, should he have immediately complied since compliance required him to reach for the object in his waistband?
I think this is where much of the Loehmann defense founders. If Loehmann told Rice to drop his weapon, then Rice reaching for the toy was an act of compliance. There is an alternative narrative being circulated that has Loehmann telling Rice to show his hands. If Loehmann told Rice to show his hands, then Rice's hands moving from his sides past his waist was also compliance.
How do you justify Loehmann shooting Rice as Rice complied with the shouted orders? Or were there no orders, and Loehmann shot Rice without trying to communicate with him or seek compliance?
#4. Should Rice have known better than to play outside with an airsoft gun given that he was big and black, and the airsoft looked like a real gun?
Is that why Loehmann shot him? Because he was a big black kid with a realistic looking airsoft gun in his waistband? It appears that most posters here think so, and some posters think the shooting was perfectly acceptable for those very reasons.
