Police Commissioner is an appointed office in Boston so, if the appointee want to keep the job, I expect him to say whatever Hizzoner wants him to say. True to that, William Evans, recently appointed Police Commissioner for the City of Boston, is quoted as saying
I don’t agree with that. Having long guns–rifles and shotguns–especially here in the city of Boston. I think we should have, as the local authority, some say in the matter. [And] the federal [government] doesn’t really allow us to have the discretion that we want in these particular cases.
…For the most part, nobody in the city needs a shotgun. Nobody needs a rifle.
A "need" for any kind of gun is not a valid criteria for determining access to a fundamental human right and letting the controlists frame that -- or any other part of the debate -- is a bad idea. Do not let an opponent blather on about "need" until he or she first agrees there is a fundamental right to effective self defense. Emphasize that "effective" in this case means that the victim will have an equal or better chance than the criminal of escaping the encounter unharmed.
Frankly, I don't think the controlists even care about what I "need" because they don't believe any of us has a right to resist criminal attacks. That is why they always argue, "Just give them what they want." The "need" argument is just a rhetorical trick to move the debate to a place where gun owners and their rights can be attacked. Concentrating on the civil rights issue provides more leverage and, believe me, the controlists hate it. They don't want to talk about rights because, deep down inside their scabby little souls, they are driven be a hate of guns and the culture that guns are a part of. I am convinced they seek the deliberate and systematic destruction of the entire unique non-criminal "gun culture".
There is no reasons that, in a sane world, I have to justify my peaceable, non aggressive choices. I don't have to give a reason why I use Linux instead of Windows or a Mac. I don't have to explain why I drink Southern Comfort or Jack Daniels nor explain why I don't drink Rum or Tequila. I don't have to justify the sex or number of people I sleep with. It is equally nobody's business but mine what kinds of guns I own nor how many rounds each will fire before reloading.
