Police in Minnesota would have to make detailed disclosures about how they use license plate tracking technology under a bill introduced in the Legislature Monday.

The legislation, introduced by Sen. Scott Dibble, DFL-Minneapolis, requires law enforcement to keep a public log of where they use license plate readers, when they collect data and how much they collect.

License plate readers are small scanners, often mounted on squad cars, that check every license plate they see against a database of wanted vehicles. But they also store location information on non-criminals.

Dibble's bill is expected to mirror House legislation sponsored by Rep. Mary Liz Holberg, R-Lakeville. Law enforcement lobbyists are likely to oppose the bills.
