MD HB682

Prohibits Maryland state agencies and political subdivisions from using persistent aerial surveillance—aircraft recording video or sequential images that track a person's actions over time—to gather evidence in criminal investigations

Requires a valid search warrant issued by a judge before persistent aerial surveillance can be conducted for criminal investigation purposes

Allows warrantless persistent aerial surveillance in specific emergency situations: executing arrest warrants, fresh pursuit of suspects, search and rescue operations, locating escaped prisoners, and preventing imminent serious bodily harm

Permits surveillance when the U.S. Secretary of Homeland Security determines credible intelligence indicates a high terrorist attack risk and aerial surveillance is necessary to counter the threat
