A CT Class D Felony makes one a prohibited person for life with a 1-5yr sentence. But it looks like the use of an “unsecured” firearms in the injury or death of anyone doesn’t apply if the person accessing/injuring/killing another made unlawful entry to the premises.
That’s a convoluted way of saying that if a resident, guest, service worker, etc., takes an unsecured gun and shoots themself or another, the gun owner is tagged with a felony. The law appears to give an out to someone whose unsecured gun is stolen in an unlawful entry and used in a shooting, as long as the gun owner report the theft within 72hr.
The really sad part is that criminals that shoot people are often given equal or lesser punishment.
