Surveillance plane starts flying over Baltimore, recording everyone's movements

The controversial aerial surveillance planes for Baltimore police started flying Friday, recording movements of everyone in the city during the day.

This is the second life of this program in Baltimore. It first operated in secret in 2016 under then-Commissioner Kevin Davis. Now, it's more public, but the debate remains the same: Is it an invasion of privacy or an effective crime-fighting tool?

You can't really see it, but the privately funded surveillance plane is flying. It's called the Aerial Investigation Research (AIR) Pilot Program, and it's operated by an Ohio-based company and is paid for by a Texas billionaire.

Police Commissioner Michael Harrison told the 11 News I-Team Friday afternoon that he's keeping expectations in check.
