The gun lobby's lawsuit against Maryland's life-saving Firearm Safety Act described in Saturday's front page article does not challenge the constitutionality of the key provision of the act — requiring handgun purchasers to first obtain a fingerprint based background check and license from the state police ("21 states hope to overturn Maryland's gun control law," Nov. 21). They did not challenge this provision because they knew they would lose — similar measures have been reducing gun violence in other states for decades with little or no objection from gun owners. And we are already seeing an impact here in Maryland with a 17 percent drop in gun deaths in our state during the first ten months of this year. Further, the state police department is doing a very good job of implementing the law fairly and efficiently so that legitimate gun owners are getting their licenses in a timely manner. Plainly, the big news about the Firearm Safety Act is that it is working well and saving lives.
