A co-worker who lives in Middleton, MA told me of a similar situation that happened to his neighbor. The guy went to the transfer station to dump his trash (apparently, they don't have curbside pickup there). Some shabbily-dressed character told him to come back later, the place wasn't open, etc. The neighbor told this character that he was on time, pointing to his watch and the business hours that were clearly posted on the sign at the entrance. He then asked the character if he worked there. The character grew angry, asked the neighbor if he had "a problem" and then pulled a badge and threatened to arrest him for disobeying an officer. Turns out he was an off-duty Middleton cop who was just hanging out with a friend at the transfer station. The neighbor did nothing wrong, legally. A few days later, the revocation letter arrived in the mail, declaring the neighbor "not a suitable person" to hold a LTC. From what I understand, he was able to get the guns into a relative's home in NH just before the police showed up with a confiscation order hours later.
Yup, it dosen't take much to be "unsuitable" in this Great State [sad2]
