Maryland Senate Democrats passed a gun-control bill that would require residents to undergo fingerprinting, and fingerprint background checks in order to get a license to buy a firearm.

The bill also includes a ban of assault weapons and magazines that hold more than 10 bullets. On the issue of mental health, the bill bars anyone committed involuntarily for any length of time from purchasing a gun. In addition, those who voluntarily admit themselves after visiting an emergency room for mental health issues may be prohibited from purchasing firearms if doctors determine that they pose a threat.

Republican, as well as some conservative Democrats, objected that requiring fingerprints would infringe upon citizen’s Second Amendment rights; while mental health professionals worried the restrictions on those who voluntarily seek treatment would discourage people from getting the help they need.

Supporters argued that the new checks such as fingerprint background checks would reduce the instance of “straw purchases,” when a friend or family member purchases a gun for someone who may not be able to.

Republicans, however, added some measures that will give more leeway to those with assault weapons, such as allowing those who currently own unregistered assault weapons a grace period to register their weapons without penalty.
