Connecticut already has an assault weapons ban.
Sec. 53-202c. Possession of assault weapon prohibited. Class D felony. (a) Except as provided in section 53-202e, any person who, within this state, possesses any assault weapon, except as provided in sections 29-37j, 53-202a to 53-202k, inclusive, and 53-202o and subsection (h) of section 53a-46a, shall be guilty of a class D felony and shall be sentenced to a term of imprisonment of which one year may not be suspended or reduced; except that a first-time violation of this subsection shall be a class A misdemeanor if (1) the person presents proof that he lawfully possessed the assault weapon prior to October 1, 1993, and (2) the person has otherwise possessed the firearm in compliance with subsection (d) of section 53-202d.
.
(b) The provisions of subsection (a) of this section shall not apply to the possession of assault weapons by members or employees of the Department of Public Safety, police departments, the Department of Correction or the military or naval forces of this state or of the United States for use in the discharge of their official duties; nor shall anything in sections 29-37j and 53-202a to 53-202k, inclusive, and subsection (h) of section 53a-46a prohibit the possession or use of assault weapons by sworn members of these agencies when on duty and the use is within the scope of their duties.
.
(c) The provisions of subsection (a) of this section shall not apply to the possession of an assault weapon by any person prior to July 1, 1994, if all of the following are applicable:
.
(1) The person is eligible under sections 29-37j and 53-202a to 53-202k, inclusive, and subsection (h) of section 53a-46a to apply for a certificate of possession for the assault weapon by July 1, 1994;
.
(2) The person lawfully possessed the assault weapon prior to October 1, 1993; and
.
(3) The person is otherwise in compliance with sections 29-37j and 53-202a to 53-202k, inclusive, and subsection (h) of section 53a-46a.
.
(d) The provisions of subsection (a) of this section shall not apply to a person who is the executor or administrator of an estate that includes an assault weapon for which a certificate of possession has been issued under section 53-202d, if the assault weapon is possessed at a place set forth in subdivision (1) of subsection (d) of section 53-202d or as authorized by the Probate Court.
They've been banned since 1993, with pre-existing guns grandfathered. The assault weapons ban they're pushing in Congress is a moot point. It would have been moot anyway since it wasn't his gun.
