I read an account that there is gunpowder residue on Zimmermans clothing too.
First I have seen on that.
Blowback perhaps? No idea what type of weapon Zimmerman had, but if you shoot someone/something from close enough you can often get residue back scattering.
KelTec 9mm. One round fired, next round did not chamber, so slide didn't cycle all the way.
Martin's clothing and flesh were burned; Zimmerman's clothing had powder residue.

Yep. I figure the point was that Zimmerman hadn't fired on a 3 or 4 foot distant target, and my impression is he did not have his arm extended. All the forensic evidence is consistent with a close quarters shot.
Yes, one would expect to find powder residue on the shooter.
>if you shoot someone/something from close enough you can often get residue back scattering.
I can vouch for that. Shooting two .44 rounds through a tempered glass storm door from a few inches away left me with
the taste of H110 in my mouth for the whole week I was in jail.
