If a person was charged with a gun and it wasn't theirs and finger prints didn't match on the gun can they charge someone else with the gun afterward. The gun wasn't used just poessession and a first defense and then accused of pointing at the cops.

If a person was charged with a gun charged and the finger prints didn't match can they go and charge someoneelse for it. That doesn't have a criminal record on file

Your location is important.

Do you mean first offense instead of defense?

Tell us the whole story, we can't give accurate advice with such little information.

If a cop picks up the gun and put it in his pocket and then put it back down can they prints are on top of other prints can they charge anyone with the gun still

Please tell us the WHOLE story.

As far as I can make out, OP was charged with possession of a firearm and assaulting a police officer with that firearm. It looks like there was a problem with fingerprints found, or not found, on the firearm. I am not sure what fingerprint analysis would have to do with possession and assault charges; normally there would be witnesses to those sorts of crimes. But, as noted, we need more information.

If the charge is illegal possession of a firearm, then the nature of that possession is a key issue. Where was the firearm found under what conditions?

If you were also charged with menacing a police officer, then it would appear the gun was in your hand and that would mean a police officer witnessed your possession.

But the others are correct. We need to understand the full story to be able to help.

If you were charge with a gun and pointing it at the police the internet is not where you should get advice, don't you have a lawyer?

They need to tell us a lot more.

If they were charged with pointing a gun at the police... they don't NEED fingerprints. They were found in proximity to said gun... they have the cops testimony that they did it, that's all they need. If the cops had a body camera like more and more police jurisdictions are using these days...then there is video evidence to back it up most likely.

Your prints do not have to be on the gun, to be changed with possession of the gun. If they gun, is anywhere near you, in your car, even if under the other seat,

If in your apartment or house, in any room that you have access to.

Yes the officer will pick up a gun, for safety and keep it, till it is safe to return it, to the position it was in, or just bag it for evidence.

His touching the gun, will not harm your fingerprints on the gun, just add his, which is OK, since he took custody of the gun and it will be listed on the legal chain of evidence.

For possession they gun does not have to be loaded. And in fact it could be rusted and not able to fire, if it is a real firearm. (We did one of those about 15 years ago, a old shotgun, rusted shut, the boy got 12 years for possession.
