Section 29 of chapter 147 of the General Laws, as appearing in the 2018 Official edition, is hereby amended by striking out the first paragraph and inserting in place thereof the following 2 paragraphs:-

No licensee or employee or agent of a licensee shall use a badge of any kind for identification purposes except a guard or watchman or security guard in uniform who shall wear any such badge on the left breast of their uniform at all times while on duty. Such badge shall include a photograph and the name of the guard or watchman or security guard, but shall not contain the word “Police” or any part of the seal of the Commonwealth of Massachusetts or of any political subdivision thereof. A licensee or their employee or agent may use as identification a card, approved as to form by the colonel of the state police, which shall bear the signature of the licensee and, if such card is used as identification by an employee or agent, the signature of such employee or agent; provided, however, that a guard or watchman or security guard shall not substitute an identification card for the badge required by this section.

A licensee or employee or agent of a licensee shall carry only such weapons and equipment as are authorized by the colonel of the state police; provided, however, that if said licensee, employee or agent, is authorized to carry a firearm, as defined in section 121 of chapter 140, said firearm shall be loaded while in the performance of their duties. Any guard or watchman or security guard in uniform who is carrying a weapon pursuant to this section shall wear at all times an identification badge on the left breast of their uniform which shall include a photograph and the name of the guard or watchman or security guard. A licensee, or their employee or agent, while in the performance of his duties, shall not carry an imitation firearm as defined in said section 121 of said chapter 140.
