In the US? Five years in Federal prison, no probation, no parole, IF he has access to the firearms.
The felon will most likely be arrested.
Felons are not allowed to possess guns, regardless of where they are.
You're obviously screwed...
No.
Absolutely not.
The basic answer is no. The short answer is, a felon cannot have access to guns, and at a gun show, a felon would have access to guns, so it's illegal.
In the U.S. a convicted felon may not own or posses a gun.
No felon can buy, posess, or live in a house or dwelling where firearms are present. Furthermore if a non-felon buys a firearm for a felon as a gift or to cover for them because they cannot pass the 4473 background check they are aiding a felon and punishable by the same prison sentence. The standard sentence for felony possesion of a firearm is 10 years in a federal prison. But that is rarely handed out. However it would greatly benefit the U.S. if it did hand out this punishment. However, to clarify part of the answer, the spouse of a felon can own a gun, as long as the spouse can otherwise legally own the gun. However, the gun cannot be stored anywhere the felon could possibly have access to it.
Notify the police.
If a felon lives with you, you should probably move far away If a felon lives with you u are bad at picking dates
Provided you are not a convicted felon, you can buy long guns at 18 and hand guns at 21.
Only if you are a felon...(None in the United States).
