Be careful, it could be a federal crime. If this is a clinic, and the feds take the case, you are looking at 18 USC 248. That may give you a civil fine, which means you can still own a gun.
A criminal conviction could be much worse. The law seems to divide the crime into two offenses, one non violent which would still let you own a gun (6 months), and one violent (one year or more) for repeat, when you may not be able to.
It all depends on how the court rules on the statute structure. Mean-while, you guns are ruined or lost, and you are in prison and poor, having spent all your money on a lawyer.They may even clump in the non-violent with everyhting else, and strip you of your gun rights on just that.
Consult with a good lawyer locally. Someone who was both in the state and fed office would be great. They can find out the real scoop on the local policies and rulings. It will cost. If you are in a big city count on much more than $1000, smaller place in the $1000ish range. You have to know, though, guns are too important to loose.
