I don't think any entity (including but not limited to the government) should be allowed to create or maintain data sets of people's near or real time location data. Think about all the ways this data can be misused.
We are truly creating the chains that will bind us by allowing these kinds of tools to exist. And for what? We managed for generations to do policing without LPRs. Are we so drowning in crime that we should create universal surveillance as a solution?
