FBI: If We Told You, You Might Sue

In 2008, a few years after the Bush administration's warrantless-wiretapping program was revealed for the first time by the New York Times, Congress passed the FISA Amendments Act. That act authorizes the government to engage in dragnet surveillance of Americans' international communications without meaningful oversight.

The government doesn't want you to know whether your internet or phone company is cooperating with its dragnet surveillance program because you might get upset and file lawsuits asserting your constitutional rights.
