This past Thursday, on June 24, the Fourth Circuit quietly issued an en banc opinion in “Leaders of a Beautiful Struggle v. Baltimore Police Department, which challenged the Baltimore Police Department’s Aerial Investigation Research (AIR) pilot program on Fourth Amendment grounds. In an opinion written by Chief Judge Roger Gregory, the Court held that the AIR mass aerial surveillance program was an unconstitutional search and seizure (at least at the point the data was accessed).
The AIR program “tracks every movement” of every person outside of a structure in the City of Baltimore, retaining 45 days worth of data which is a “detailed, encyclopedic” record of where everyone came and went within the city during daylight hours. Law enforcement can “travel back in time” to observe a target’s movements, forwards and backwards. The Court likened the data to “attaching an ankle monitor to every person in the city,” and noted that, “whoever the suspect turns out to be, they have effectively been tailed for the prior six weeks.”
The Court held that “because the AIR program opens “an intimate window” into a person’s associations and activities, it violates the reasonable expectation of privacy individuals have in the whole of their movements.” Whereas traditional aerial or static camera surveillance have been upheld as reasonable by the courts, those cases “all involve some discrete operation surveilling individual targets.”
The AIR program records the movements of a city. With analysis, it can reveal where individuals come and go over an extended period. Because the AIR program enables police to deduce from the whole of individuals’ movements, we hold that accessing its data is a search, and its warrantless operation violates the Fourth Amendment.Opinion at p. 28
The AIR program is like a 21st century general search, enabling the police to collect all movements, both innocent and suspected, without any burden to “articulate an adequate reason to search for specific items related to specific crimes.Opinion at p. 32
Since this holding came from the Fourth Circuit sitting en banc, the only where to go from here is to the U.S. Supreme Court.
Mr. John, are the ALPR (Automated License Plate Reader) against the 4rth amendment as well? Just found out that my town has them and are purchasing more of them.
It’s going to the Supreme Court and this court will take the plain view position.
