The editorial discusses Maryland's new internal-trigger-lock law for handguns that took effect on January 1, 2003. It notes that gun dealers have known about the law for three years but are now claiming it will threaten their livelihoods. The editorial argues that the law could help reduce accidental gun deaths and acknowledges opponents' concerns, but maintains that public safety should be the top priority. It concludes by urging Governor-elect Ehrlich not to weaken the important safety measure.
