Depends on what the felon was charged with.
Yes. Possession of stolen property OF ANY TYPE, is illegal.
It can depend on several factors, chief among these being YOUR criminal status, if any. If you are a felon in possession it could be both a state and/or a federal case.
Yes, any person who has been convicted of felony or is on parole is forbidden to be in possession of a firearm and could be federally charged if the authorities find out.
Personally I am unfamiliar with the LA statute but in many (most?) jurisdictions whether it is classified as a felony or a misdemeanor depends on the dollar amount of the property in question. (e.g.: possession of a stolen tricycle would be a misdemeanor, but possession of a stolen truck would be a felony)
Yes
If the possession charge was a felony, no, it is not legal to own or possess a gun.
Maybe - maybe not. If the gun was involved in a violent felony and you are in possession of it, yes, you could be charged with that violent felony. Even being IN a car with a gun places you in, what is called, "concurrent possession" of that gun.
In most states it would be a felony.
Yes.
no
Yes, and it could be a felony.
It depends on whether it was FELONY possession or MISDEMEANOR possession. If FELONY, no, you cannot ever again own or possess a firearm.
You need a lawyer for a current, legal and correct answer for your situation.
This is a felony crime.
Not enough information to answer. What is making the possession of it "illegal?" Was it used in an unlawful manner? Is it a stolen weapon? Are you an adjudged felon?
