Why not fired?

An offduty cop fires his "off-duty" handgun, and then lies about the situation to cover for his negligence. This stood out in the article.

Greg W. Kennedy, 29, of 11 Maude Terrace, speaking briefly on the steps outside his home yesterday, said the incident has cost him his firearms permit and may cost him his full-time job at a private security company, but he expects to keep his part-time job as an officer with the Randolph Auxiliary Police Force

It "may" cost him his off duty job, but he "expects" to keep his police position. That somehow seems backwards. Shouldn't the police have higher standards then a mall-cop?

This either implies how hard it is to fire a cop, or how little the police care what their employees do.
