The Second Amendment of the Constitution does not protect convicted felons.
NO
YES
Unless there is some prohibition against leaving the state contained in the parole or probation papers, or there is a court order prohibiting it, then probably, yes the convicted felon can move state to state.
It depends on what you mean, but generally speaking, a felon can't get a gun license.
In addition to California law that makes possession of a firearm by a convicted felon a STATE felony, Federal law prohibits possession, and requires a 5 year sentence, without probation or parole.
It may not be illegal for YOU to own it - but - if it is in the same house as the convicted felon he may be deemed to be "in possession" of it. A convicted felon is prohibited by federal law from owning or POSSESSING firearms (USC, Title 18). If it comes to it, you MIGHT be charged with "aiding and abetting."
If you are a convicted felon who has completely satisified all the sentence imposed on you by the court, no.If you are a convicted sex offender, yes, you must.If your parole has been transferred (by the court) to California from whatever state you were convicted in, yes, they MUST be notified as well.
With a really good laywer, lots of money and patience; maybe.
