Last time we went through this I looked up the regulation. I'm too lazy to go find it again, but the end result was that carrying a gun at Logan is civil offense punishable by a small fine ($100, I believe).
It was >30 years ago, but this story is probably worth telling (again) to point out a few things. Remember, in those days there was NO Internet, NO online way to check MGLs or CMRs to verify any info easily.
I used to shoot with a criminal law attorney who carried all the time. My MIL was flying into Logan and I was going to pick her up, so I asked about carrying in the non-secure area and a way to check the gun to meet her at the gate. My lawyer friend told me he did this all the time and checked his gun at the security checkpoint with a MA State Trooper (back then they supervised the security checkpoints).
I called "F Troop" to verify the info. Unknown to me the phone call bounced to 1010 Comm Ave (MSP HQ) and a Corporal Belloff told me that I could indeed do what was stated above by my lawyer friend.
I arrived at Logan, go to the checkpoint and ask the Trooper to hold onto my firearm while I went to meet my MIL at the gate. He asked if I was LE (this was before I joined the PD) and then told me
"it was illegal to possess any firearms on ANY MASSPORT PROPERTY". I explained that Cpl. Belloff had told me that I could legally do this . . . he reiterates that it is illegal, says he won't hold anyone's firearm and suggests that I go up to the Turret (MSP F Troop HQ) and check it there. The Sgt at the desk doesn't mention anything about it being illegal but refuses to check the gun. By now, my MIL is "on the ground", so I just leave and wait for her outside the secure area.
Lessons learned:
- Ask 3 MSP Troopers a firearms question and get 3 different answers!
- If it were really illegal to possess a firearm "on any Massport property" (never did find out) this could be a major problem: No transporting/carrying on the Mass Turnpike, Mystic River Bridge, Airport property, no bringing any firearms on airplanes to go hunting or anything else.
- Since CMRs are administrative laws and don't undergo any real scrutiny for legality/constitutionality, etc. who knows what some admin dweeb "created as law"!
- Remember this was >30 years ago, when MGLs on firearms were a LOT SIMPLER! Today, with >400 pages describing MA gun laws, literally nobody knows all the laws and admin laws (CMRs) and how they would be interpreted at any location/time!
