The missions were non-military in nature, meaning they were used for domestic spying purposes. Naturally, the Pentagon is claiming it broke no laws in the deployment of said drones and contends that the flights were rare.

A senior policy analyst for the ACLU, Jay Stanley, said it is good news no legal violations were found, yet the technology is so advanced that it's possible laws may require revision, according to USA TODAY.

"Sometimes, new technology changes so rapidly that existing law no longer fit what people think are appropriate," Stanley said. "It's important to remember that the American people do find this to be a very, very sensitive topic."

"The appetite to use them (spy drones) in the domestic environment to collect airborne imagery continues to grow, as does Congressional and media interest in their deployment," stated the report, quoting a military law review article.
