contacted attorney...he said NEVER disclose your arrest and legally I can say I have never been arrested or been a defendant......I did not..got permit...and have a couple from other states...never had an issue.
I'll save you the trouble of a legal consult:
1). What the attorney is referring to is the concept of "legal fiction". In certain states, you are entitled to answer "NO" to "have you ever been arrested, charged with or convicted of a crime?
when asked if you have an expunged record. Your statement is untrue in the plain English sense of the word, but considered "legally true", hence the term "legal fiction".
2). MGL is silent regarding the concept of "legal fiction" with regards to firearms licenses, however, the most common reaction you will get if a licensing officer finds out is "you were in fact arrested, you lied, no license". In some cases, the officer may accept your explaination of "legal fiction" and give you a chance to modify your application - but your chances of getting denied, or perhaps even prosecuted for lying on the app, are greater than that of "getting a pass".
3). What the licensing agency will find out is a crapshoot, and it is VERY hard to tell, with certainty, if the licensing authority will find our about a sealed or expunged record from another state. If the sealed record is from MA, consider that a high ranking state employee has a standing offer to PDs to assist in any way possible if they have trouble accessing a sealed record for licensing purposes.
4). The MA system contains much more subjectivity that many other states, and the fact that you got permits in other states, while a positive sign, is not an assurance that an expunged/sealed record will not cause a problem in MA.
5). As SCaflin states, it is a crapshoot. If you withhold information, you need to be certain that you are entitled to the "legal fiction" of doing so.
However, I have seen an applicant "caught" legally withholding information pertaining to his expunged out-of-state record, and he was subsequently issued his LTC after sending documentation that showed he did not need to legally disclose the information. This was in a red town too.
My guess (correct me if I am wrong) is that the fact that you saw this indicates said individual needed to retain the services of counsel, and pushed the cost of his LTC up into the 4 digit price range.
