If unknowingly, that is not a crime.
Yes
5 years and up.
A felon who is an ex-con can hunt in Mississippi - however, they may not do so with a firearm. To be an ex-felon, any and all felony convictions must have been overturned, and the conviction reversed.
As far as the U.S. is concerned, yes, you can, especially if there is any evidence that you knew the person was a felon. U.S. law forbids a felon from owning or possessing a firearm, and forbids a person from knowingly giving or selling a firearm to a felon.
I believe nothing, as long as you have the proper permission to sell guns.Added: REALISTICALLY - If the weapon can be traced back to you via the serial number OR the felon rats you out as the seller, you will have to do a L-O-T of convincing and explaining to law enforcement that you did not know the true background or identity of the individual you were selling the firearm to.
A felon can be "around" a person with a firearm as long as the felon doesn't own or possess the firearm, however, "possess" is subjective. If the felon can access the firearm, it might be considered possession if something were to happen.
No, he cannot have a firearm.
Yes, but firearm must be under lock and key and NOT accessable to the felon
No
Being pardoned does not allow a felon to possess a firearm. Only an overturning of the conviction can do that.
No
No, all felon firearm laws still apply.
