How’s you meet the rando to sell the gun? Was there ever electronic communication between you two? Did you ever post a picture of the gun somewhere?
There are always a lot more than just the guys word against you, to convict you. And I’d imagine MSP and the DA will leverage whatever they can if joe rando ends up involved in a serious crime and fingers you as having provided the gun.
Many states it is not legal to consume alcohol for minors under your roof.
On the new firearm, my point is if the firearm was sold new after the enacting of this law. You sell it later or someone sells it to you, pretty easy to prove you guys broke the law as the trail stops at the FFL who last sold it with no records from another FFL proving you guys followed the law...
Not sure if MSP will run stings, but I’d bet some will happen. Do cops never run stings on gun or drug sales? Seems you hear cases of cops staking out gun shows often enough looking for whatever. Are you really telling me no departments will have the resources or inclination to run a sting? If so, I have a bridge to sell you.
