New York (CNN Business) A criminal justice plan from presidential candidate Bernie Sanders would ban police from using facial recognition software.

The Democratic senator and 2020 hopeful also called for a pause of the use of algorithmic assessment tools in the criminal justice system until they are audited.

"We must ensure these tools do not have any implicit biases that lead to unjust or excessive sentences," the Sanders proposal outlines.

An extensive ProPublica investigation in 2016 detailed how algorithmic systems used to predict future criminals were flawed.

Facial recognition can be used to identify people from live video feeds, often by comparing facial features with a database of faces, such as mugshots.
