Ingham County Sheriff Gene Wriggelsworth said that he still has concerns with having an armed public. Too bad, Gene.
"If the cops show up to the scene and the person with the CPL and the bad guy are fighting, how do the police know who's responsible for the crime?" While that is a remote possibility, the far more likely scenario is that the encounter will be over (relatively) long before the cops show up. Could it conceivably happen? Yes. Is it likely to happen? No.
