This might be a good time to rehash the "don't lie" thread.
I've been to court. I've seen what happens. There isn't a law against "gun running". They don't prosecute for the crime of "straw purchase." What they prosecute you on is "lying on a federal form". That's it. Paperwork violation.... 5 years.
(Yes I understand that buying the gun for someone else is illegal and is called a "straw purchase", but what they actually take you to court on is the little box you checked and swore to that the purchase was for your own personal use. Paperwork violation.)
Same if it comes down to confiscation. If you lie to a LEO, and they find the gun in your house, they won't prosecute you for having the gun, but for lying. Actually they'll probably plea bargain it using that as leverage.
Here's the advice from that old thread. KEEP YOUR MOUTH SHUT. If a LEO asks you about a gun. DON'T ANSWER. DON'T MAKE THINGS UP. Just say ..... NOTHING. Don't quote the 5th or anything else.
If in the worst case scenario and they trash the 4th amendment, they'll have the search warrant in their hands when they come the first time. Remember, even though you haven't been read your rights, anything you say can still be used against you. ESPECIALLY if you LIE. Also remember NOTHING, NOTHING you say will be used in your defense.
