2nd, Tamir Rice didn't have time to draw or drop the toy. The police didn't know if he was going to draw his weapon or drop it on the ground. He never had time to do anything BUT die. In fact, they didn't even give him time to show the tip and therefore see if it's a toy or not.
So to answer your question, yes. Give him time to relinquish the "weapon".
3rd, you and others keep repeating the lie that Tamir Rice pointed the toy at the officers. He never actually pointed anything at the officers. The other lie is to continue to call the toy he was holding a weapon. It was not a weapon, even though it looked like one.
