 A plan is being put forward to make apartment buildings safer in the nation's capital. The bill from D.C.'s Attorney General would require upgrades, better lighting and self-locking exterior doors for buildings with five or more units. It would also expand the scope of the Nuisance Abatement Act in D.C. to include serious crimes involving guns. That would allow the AG's office to file lawsuits against properties where violent crimes involving a firearm happen.
