In "The Market for Liberty", Linda and Morris Tannehill argue that a private defense agency would be unlikely to engage in aggression, as it would not only become a target of retaliatory force, but would become the subject of severe business ostracism. They suggest that honest and productive individuals would dissociate themselves from it, fearing that it might use its aggressive force against them in the event of a dispute; or that they might become accidental casualties when retaliatory force is used by one of its other victims; or that their own reputation would suffer due to their ties to it. Moreover, they say private defense agency's reputation would suffer and it would be regarded as a poor credit and insurance risk, the latter due to the high risk of claims resulting from its involvement in aggression. The employees and leaders of such an agency as well could face personal civil liability for their involvement, and the agency would not be shielded by sovereign immunity. High-quality employees would presumably be less willing to be involved with such an organization.
