Having it expunged doesn't restore your firearms rights - you remain a convicted felon, and thus, are prohibited from possessing a firearm under federal law. If it is only a felony at the state level, it MIGHT be possible to have your firearms rights restored. You'll need a lawyer to give you a more insightful answer here. If it's a federal felony, you can pretty much forget it.
Insufficient information given on which to base an answer. Was it felony battery or misdemeanor battery?
No. I think the Lautenberg Act of 1996 covers this.
As long as that person can otherwise legally own the firearm.
no...
no
You problably can, just make sure you have a permit and are legal of age.
accused - yes; convicted - no
Depends on the misdemeanor, and whether you were convicted or not.
--------- Not enough info to answer. What kind of "illegal gun?" Is the weapon illegal or is the person possessing it, in illegal posession of it (i.e.: convicted felon, or convicted of domestic violence)?
Yes, especially if you have been convicted of a crime against a family member/ domestic partner.
no
You will have to get a lawyer. To many variables involved for a simple yes or no answer.
Louisiana doesn't have gun registration to begin with.
