Several .223 caliber rounds near a Bushmaster XM-15; the manufacturer's owner is putting its gun companies up for sale.

(CNN) -- In the 1970s and '80s, when corporate America was plagued with inefficiency, a new class of financially motivated takeover investor emerged to prey on the fattest in the corporate herd and scare the rest into line.  Today, as pockets of corporate America are plagued with immorality, we need a new class of socially motivated takeover investor to prey on the sociopaths in the corporate herd, turn them around and perhaps scare (or shame) others into line.  The upcoming sale by Cerberus Capital of the Freedom Group, the largest gun manufacturer in the United States, is a perfect opportunity to usher in this new era of muscular, socially responsible capitalism:  First, Michael Bloomberg, George Soros, David Geffen and the like should establish a nonprofit SPAC (Special-Purpose-Acquisition-Company) called BidForFreedom.org (BFF) with a mission to reduce needless deaths through gun violence in the United States and encourage the passage of sensible gun control regulations.

They should appoint George Clooney, Angelina Jolie and Matt Damon to the fundraising committee and recruit a loud-mouthed, poison-penned, but good-hearted activist hedge fund titan as chief investment officer (Bill Ackman? Dan Loeb?).  Opinion: Forgotten victims of gun violence  To be credible, BFF will probably need to start with at least $250 million in cash and commitments (no problem given the billionaire status of the sponsors) with additional firepower raised as needed from well-heeled individuals, foundations and through a broad-based Internet solicitation to an outraged-by-Newtown public.  Second, BFF should lobby all public pension funds that are part owners of the Freedom Group (by virtue of their investment in Cerberus) to roll their investment into BFF to reduce the need for outside funding, naming and shaming any unwilling public investors.  Third, BFF should pay "whatever it takes" to acquire control of the Freedom Group in the upcoming auction by Cerberus (which has a fiduciary obligation to sell to the highest bidder) and then immediately implement a "moral turnaround" plan under which the Freedom Group:  (i) Appoints a high-profile CEO with impeccable credentials as a hunter and/or marksman who is nevertheless in favor of gun-control.  Opinion: Guns endanger more than they protect  (ii) Elects a new board of directors including representatives from the families of victims killed in Newtown (and/or other massacres perpetrated with Freedom Group weapons), military veterans and trauma surgeons with real experience of human-on-human gunfire, and law enforcement and mental health professionals.  (iii) Operates the business as if sensible gun laws were in place (this may turn out to be a wise investment in future-proofing the company): discontinuing sales of the most egregious assault weapons and modifying others as necessary so they cannot take huge-volume clips; offering to buy back all Freedom Group assault weapons in circulation; micro-stamping weapons for easy tracking; and providing price discounts for buyers willing to go through a background check and register in a database available to law enforcement.  (iv) Voluntarily waives its rights to support the NRA and other lobbying groups.  (v) Creates a fund to compensate those who, despite its best efforts, are killed or wounded by its weapons.  (vi) Agrees that if the effort to provide moral leadership in the weapons industry doesn't succeed within a year, BFF should consider corporate euthanasia, even though it entails a risk of allowing more retrograde manufacturers to fill the void in the market left by the then-deceased company.  Opinion: The case for gun rights is stronger than you think  In the face of horrors like Newtown, BFF would recognize that it's time to take a stand by acknowledging the impossibility of reaching closure after such a monstrous act while an unreconstructed Freedom Group continues to sell a huge volume of guns and ammunition rounds each year even if it is operating under new owners.  Like any Trojan Horse strategy, this is a long shot, but it must be tried. History suggests that only after the first company "turns" will an industry gradually return to the realm of the human (think of big tobacco). And without the tacit agreement, if not the outright support, of at least one important insider, policymakers seem utterly unable to pass tough regulations in the face of the predictable, but withering, assault by industry lackeys shrieking that any such regulation would be "impossible, impractical or too expensive."  In the face of a recalcitrant industry, we have to acknowledge that it is only the market for corporate control -- the real possibility that an outsider will take over one of the companies -- that puts limits on the behavior of board members and executives who, while perhaps decent enough in their family lives, display a limitless tolerance for the "banality of evil" at the office.  Opinion: Not man enough? Buy a gun  We must accept that the conventional, kid-gloves approach to socially responsible investing -- divesting shares in "bad" companies that nevertheless continue to exist -- is too weak an instrument to force change and its well-meaning practitioners too soft to enter the fray when emotionally and politically charged battles need to be fought.  And regardless of the viability of socially motivated takeovers in general, the Freedom Group looks like a great target. Cerberus is a motivated seller, the political macros look favorable, and it's a bite-sized company compared with many of the larger sociopaths in the corporate herd.  I'm even cautiously optimistic that the current impasse over gun regulation is a bad-equilibrium that few consumers actually want, and that a reconstructed Freedom Group, fighting for sensible change as a fifth column from within the industry, might well find that many people -- even a significant portion of the NRA's members -- would buy from a truly responsible (and high quality) gun maker if given the chance.  All in all, it's a pretty exciting deal, so if Mike and George are up for it, count me in.  The opinions expressed in this commentary are solely those of John MacIntosh.
