Of course the alternative theory that it's there for control and manipulation is more likely.
Either that or the NSA just isn't doing anything to stop these shootings. We may never know.
Parallel construction is a law enforcement process of building a parallel—or separate—evidentiary basis for a criminal investigation in order to conceal how an investigation actually began. In the US, a particular form is evidence laundering, where one police officer obtains evidence via means that are in violation of the Fourth Amendment's protection against unreasonable searches and seizures, and then passes it on to another officer, who builds on it and gets it accepted by the court under the good-faith exception as applied to the second officer. This practice gained support after the Supreme Court's 2009 Herring v. United States decision.

In August 2013, a report by Reuters revealed that the Special Operations Division (SOD) of the U.S. Drug Enforcement Administration advises DEA agents to practice parallel construction when creating criminal cases against Americans that are based on NSA warrantless surveillance.
A web form for sending, and storing the results of Section 702 information requests. Those were targeted requests for user data.
You can legitimately quibble over how precisely targeted they were, or whether there was a justifiable trail of evidence leading to a warrant. It, however, was not a mass surveillance system. You can't build a mass surveilance system on a 200k budget. You can't even integrate with one on a 200k budget.
Snowden's leaks showed the NSA collects data from google. Google would have no power to stop them from taking whatever they want and they seem to want everything.
Lavabit tried to provide a service where everything was encrypted and secure but the government demanded they compromise the service so they could spy on people or shut down. They decided to shut down. You think our 3 letter agencies are shaking down small tech-savvy email providers while ignoring a target like Google? A company that is devoted to collecting our personal info?
