In the same way, not wanting to let the police have this technology due to concern of surveillance is appealing to fear. People forget that, in the USA at least, the police investigate and pursue crimes that have already been committed. They do NOT pursue crimes that have not happened and do NOT scan for people who have not committed a crime. As you all should know, license plate scanners, for example, are looking for specific plates of people who have already committed crimes.
