Shield Our Streets Act of 2013 - Authorizes the Attorney General to carry out a program, through the Office of Community Oriented Policing Services, to award grants to assist eligible local law enforcement agencies with hiring and training new law enforcement officers and with rehiring career law enforcement officers who have been laid off as a result of budget reductions.
Defines an "eligible" local law enforcement agency as one that has jurisdiction over all or part of a county or other unit of local government that has a violent crime rate at or above the national average and that has had budget reductions during the most recent five-year period (elevated need locality).
Authorizes the Attorney General to carry out a program to award grants to units of local government that have jurisdiction over all or part of an elevated need locality to enhance public safety in such jurisdictions, including by: (1) purchasing public safety equipment, (2) funding public safety programs, (3) making infrastructure improvements, (4) purchasing and installing lights to deter crime, (5) funding activities related to crime labs, and (6) funding public defender programs. Authorizes such grants to nonprofit organizations that operate in elevated need localities to carry out programs designed to reduce crime in such areas.
