Theres 2 ways for this stop to go down,
1. Officer calls or notifies issuing authority, LTC is suspended / revoked. A court appearance maybe necessary, a fine maybe required, a lawyer maybe needed. Once this happens no LTC may be issued by any other town in Mass until reinstated by the agency that took negative action on it. As well as all future applications in state or, to any other state will also need to disclose the suspension / revocation.
2. Officer doesn't call, nothing happens.
None of this can be predicted. Ever.
There are so many variables in play that its always at best a 50/50 raffle with your LTC, guns, ammo, pepper spray, wallet, and reputation at risk.
I guess to quote Dirty Harry: The question is do you feel lucky?
