Great Question

A number of unidentified cell towers not belonging to cell carriers like Verizon and AT&T have been spotted around the U.S. that are picking up routine cell calls and doing who knows what with them. As the article points out, the NSA doesn't need this technology to make its intercepts (that's a whole separate issue) so who is behind these and what are they doing? Great question. Is anybody asking?
