Police officer first to arrive on the scene states in his report that he took the gun in its holster from Zimmerman’s waist. (Closeness allowed him to observe wet, grassy back)
In a later news conference it was reported that the cartridge had NOT been expelled from it’s chamber. Freepers said some thing would have blocked this.
Police have gun and Zimmerman’s clothes.
It was reported that they struggled over the gun.
Is it possible to shot a gun without aiming and shooting it?
In order for the spent cartridge to be expelled, the pistol's slide has to cycle. This cycling could have been prevented by:
1) Somebody's hand holding the slide, which would support the argument that there was a struggle for the gun, or
2) The back of the slide being in contact with something that prevented its rearward motion (for example, if the back of the gun's slide had been in contact with Zimmerman's body)
The first scenario above seems more likely to me.
There was a story a couple days ago where a little girl was jumping on her parents' bed. A gun under the mattress went off, and wounded her in the leg. So yes, I suppose it is indeed possible. So if Martin was jumping on George, perhaps the gun under George went off.
