It depends on the state.
First, there is a statute of limitations on the crime of stealing the weapon. The fact that the firearm was stolen may not be subject to the Statute of Limitations. So anyone that comes in possession of the weapon is in effect, committing a new crime.
Second, LA has a law that reads "Knows or should have known that the firearm was the subject of a robbery or theft." That someone "should have know" a certain weopon was stolen might be a tough sell, it doesn't mean that an individual is immune to being charged.
Another View: The question is unclear on whether the gun theft happened 30 years ago or the possession offense took place 30 years ago.
If the gun theft occurred thirty years ago, but the gun was just now found in this person's possession, then it is a fresh crime and a fresh charge.
It makes no difference how long ago the gun was stolen. The theft may be 30 years old, but the possession is occurring in present time - now.
Each firearm can be a different charge. 10 firearms means 10 different counts.
Yes, it is illegal to possess a firearm while under the influence of alcohol or drugs, and you can be charged with a crime for doing so.
Yes, it is illegal for an unlawful drug user to be in possession of a firearm under federal law.
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?
Burglary , illegal possession of a firearm and larceny .
Given the tone of the question, I'm going to assume that the firearm is illegally possessed, in which case, you'd be arrested and charged. If your possession of the firearm is legitimate, then you'd have no need for concern, so long as you weren't doing anything illegal with the firearm.
It depends. In Tennesee, there is a charge for illegal possession of a firearm, which is simply carrying an unauthorized firearm, and can be a misdemeanor. There is also "intent to go armed" which can be a felony. If the gun is not loaded, the charge will probably be the former, if the officer doesn't think you were up to anything bad.
Assuming something about the firearm or the manner in which it was transported is illegal, usually whoever is closest to it will be the first one to come under suspicion. If there's doubt, everyone in the vehicle can be detained and question until someone admits to possession of it.
check with your local police department for the answer.......................
Depends on what the felon was charged with.
It is having a firearm under your control when there is a law that says you cannot. It may be that you have it physically in reach, or that you control access to it (have the keys to a safe)
You will have to contact your military recruiter for the final answer. I suspect that if there is no record of a conviction, you will make it.
