Cops can’t do cell tower mass surveillance ‘dumps,’ court rules
A federal judge in Nevada has ruled that it’s unconstitutional to obtain swaths of cellular records through “tower dumps” — but will still let police get away with using it as evidence, as reported earlier by 404 Media and Court Watch.
With tower dumps, authorities can dig through the cell records that pinged off a particular tower during a specific time. Though police may be looking for just one record, these dumps often expose the data of thousands of people, making it a major privacy concern. In a 2010 case involving the High Country Bandits, for example, officers caught the two bank robbers by looking through a tower dump containing more than 150,000 phone numbers.
