I don’t live in Connecticut, but in this state you have to get a handgun permit before you can purchase a handgun in a store. The rules here at gun shows are more relaxed than the rules in Connecticut for gun shows according to the chart.
I thought it was strange that the gun store where Nancy supposedly purchased her guns was raided after the shootings. If she legitimately bought her weapons and they were all legal, why was it raided?
Probably because there is no permit required to own those guns in Connecticut just to conseal/carry but records of purchase must be kept by gun shops and they wanted copies of those records for their investigation before they could get lost.
