Keith Langer has significant experience in the preparation of license applications, appeals of license denials, FLRB appeals, and criminal defense in the Massachusetts state court system. He is a former appointee to the Firearms Licensing Review Board.

Attorney Langer has assisted Comm2A with several important cases, including denied renewals of those given relief by the FLRB, and filing amicus curie briefs with the Massachusetts Supreme Judicial Court in Comm v. Reyes and Chardin v. Boston Police. He prepared the amicus briefs on behalf of Comm2A for Caetano “stun gun” case, including the brief for the US Supreme Court. The Supreme Court summarily reversed the Mass. Supreme Judicial Court, and remanded the case, along lines argued by Comm2A.
