If you have a pending felony case, no. If you've been convicted of a felony, no. If you've been acquitted of a felony, then you can.
Arrested? Yes. Convicted? Not if the assault was a felony, or against a domestic partner.
No
If the case has closed without a finding of guilty, you have not been convicted of a disqualifying offense. You would be able to buy a gun.
No.
Nope
No
If conviction was for an offense that would have been a felony if committed by an adult, then no.
Unclear what is being asked. If the person you purchased the gun for is a convicted felon, yes, she can be arrested if she still has the gun in her possession (meaning in her home or her vechicle, or ANYWHERE where she has access to it.
No, not until acquitted.
A convicted felon is generally prohibited from possessing a firearm of any type. If you have been convicted of a felony you maybe arrested for simply having a gun in the house. If you are awaiting trial, you may be forbidden from having a weapon by your release documents. If you were charged and not convicted then there is probably no restriction on owning or registering a gun.
Yes it could be.
ANY felony conviction is a bar to possessing a firearm in the US.
