someone go ask green for written permission to bring firearms onto those sensitive places, so that you can participate in the buyback.
You cannot get permissions for sensitive places. 1250 Punchbowl is owned by the state and so is it's parking lot. The law states:
" "§134-A Carrying or possessing a firearm in certain locations and premises prohibited; penalty. (a) A person with a license issued under section 134-9, or authorized to carry a firearm in accordance with title 18 United States Code section 926B or 926C, shall not intentionally, knowingly, or recklessly carry or possess a loaded or unloaded firearm, whether the firearm is operable or not, and whether the firearm is concealed or unconcealed, while in any of the following locations and premises within the State:
(1) Any building or office owned, leased, or used by the State or a county, and adjacent grounds and parking areas, including any portion of a building or office used for court proceedings, legislative business, contested case hearings, agency rulemaking, or other activities of state or county government"
So if the gun is in your trunk, then you aren't posessing it. But if you were to walk on property with the gun in a locked case and you're a CCW holder, then you're breaking the law.
