(WAVY) — A bill concerning Flock cameras and the data they hold was just signed into law by Virginia Gov. Glenn Youngkin, with the law meant to regulate the data and add restrictions. Not everyone, however, will be happy with it.

Controversial, these cameras can capture every detail of a car — license plate, color, make, model and identifying marks. They’ve been taken to court more than a few times.

“Related to government surveillance, especially in criminal cases. And courts even in Norfolk have said that they’re not constitutional,” Attorney Tim Anderson said.

To help bring them closer to constitutional compliance, the General Assembly is limiting the use of data collected to specific criminal investigations, human trafficking, stolen vehicles and missing persons cases.

“This person abducted a child, they were driving a Toyota Camry, this is the license plate number, and law enforcement can quickly go and start looking at where they came through,” Anderson said.

The data would also only be stored for 21 days. The cameras have proven useful in locating and capturing suspects across Hampton Roads — and this bill would put this crimefighting tool to use across the state, expanding the use of the cameras to include state highways, a move that could greatly help the crackdown of human trafficking.

“It’s a big problem here, in every way,” Anderson said. “If law enforcement knows, for instance, that a van carrying minors is traveling into Virginia, it could use Flock cameras to track down where that van went.”

The bill, which is trying to make both sides happy, still has its detractors.

“Where the real, bitter concern is coming from is going to come from immigration advocates that believe that this is going to be used to hunt down and locate people that might be illegally in the United States,” Anderson said.

And many say it’s still government overreach.

“But you are turning yourself into a 24/7 surveillance state,” Anderson said. “And fundamentally, the balance between creating constant surveillance over citizen movement, and trying to do good and help law enforcement have tools, is a balancing act and on this point. You’re not going to find anyone really happy on ether side.”

The new law takes effect July 1.
