The Charlotte homeowner who shot and killed violent repeat offender Timothy Quinn yesterday did what you and our criminal justice system could not — would not? — do. Namely, get a proven predator with felony convictions stretching back a decade off of our streets.

Now this is what you do. You let the police finish questioning the homeowner. Maybe CMPD can get leads on other crimes that way, maybe Quinn cased the home in some way. Then you take the report on the incident, call the homeowner and thank him. Do not even think about filing charges.
