I think the difference is is the scope.<p>For example: <a href="http:&#x2F;&#x2F;gizmodo.com&#x2F;feds-are-spying-on-millions-of-cars-with-license-plate-1682016561" rel="nofollow">http:&#x2F;&#x2F;gizmodo.com&#x2F;feds-are-spying-on-millions-of-cars-with-...</a><p>The Feds are tracking millions of vehicles traveling interstate highways. I heard at a conference that LPR data can at a minimum provide vehicle location and in some cases historical imagery and video through the I-95&#x2F;I-81&#x2F;I-87 corridor from Florida to Canada.<p>That&#x27;s different than taking security footage at a bank robbery and putting out a bolo for a White Ford Bronco, plate 12345.<p>There&#x27;s a similar controversy about Facebook facial recognition. My face isn&#x27;t a secret -- but at some point large entities (commercial or government) tracking my movements crosses a line that is something more than observation of publicly viewable data.
