It is my understanding that the term “all lawful purposes” was developed by the MA Chiefs of Police Association as an accepted term intended to limit their liability legally, fiscally, and politically in case an LTC holder used a firearm in a nefarious manner. Inevitably the Anti’s would ask “How did this person get a gun?” and the COP could answer “Hey, I issued them a permit for all LAWFUL purposes...”.
Given it’s origin, I find it ironic that some P.D.s won’t accept the term “all lawful purposes” as a condition for issuance of an LTC.
I believe not accepting “all lawful purposes” is an attempt to limit your license by applying restrictions based upon your answer and in an attempt to deter you from applying. I feel the same way about “interviews”.
