Delegate Jackie Glass discusses a new policy proposal she is developing around encrypting data from license plate readers used by police. This is in response to the increased use of license plate readers across Virginia. Glass explains how license plate readers work - they are cameras that photograph license plates and collect data on plate numbers and locations. However, there are concerns around privacy, potential misuse of data, and predicting people's movements through machine learning algorithms. Glass wants to balance public safety with privacy protections.
