In late October, a group of Maryland legislators met with police officials, attorneys, privacy advocates, and policy analysts to discuss creating a legal framework to govern aerial surveillance programs such as the one the Baltimore Police Department had been using to track vehicles and individuals through the city since January.
“What, if anything, are other states doing to address this issue?” Joseph Vallerio, the committee’s chairman, asked the panel.
“Nothing,” replied David Rocah, an attorney with the ACLU. “Because no one has ever done this before.”
The Baltimore surveillance program broke new ground by bringing wide-area persistent surveillance—a technology that the military has been developing for a decade—to municipal law enforcement. The police department kept the program secret from the public, as well as from the city’s mayor and other local officials, until it was detailed in August by Bloomberg Businessweek. Privacy advocates, defense attorneys, and some local legislators called for the program to be suspended immediately, until the technology could be evaluated in public hearings.
