HUH??? You don't know what you're reading. I did that job for 20 years. Sit down and READ what you linked and you'll see all the safeguards for due process. You talk about our intel community like the 60s' radicals talked about the U.S. military.
When you're in a live operation and some metadata provide some potential terrorist-link returns, you don't have time to go running to some regular federal judge. You need a mechanism that can give you temporary, provisional, conditional authority to act on the metadata. If further review determines that there was no actionable information or no indications of wrongdoing, the matter is dropped.
Nope, you don't know what you're talking about. Napolitano is right.
This the FISA ruling showing that the NSA was in breach of their own protocol.

They were sharing information on US citizens with the FBI among other things. The US code was amended to bring the breaches within the law. Trump signed it, proving Napolitano correct. Trump can't be trusted to safeguard the constitution.
Napolitano is a stand up dude. I like people with convictions and that refuse to succumb to the lesser of two evils guilt trip.
And why were they sharing that information with the FBI? Why did they do that? Do you care?
The law was amended so that hyper-picky judges can't prevent vital intelligence sharing and operations by a narrow, draconian reading of the law.
And if more Americans had had Napolitano's "stand-up convictions," we would have President Hillary, a 5-4 liberal majority on the Supreme Court, no tax cuts, no repeal of the Obamacare mandate, no deregulation, no declawing of the EPA, no dozens of conservative judges put in district and appellate federal judicial positions, no cancelling of the insane Iran nuke deal, no pulling out of the absurd climate accords, etc, etc., etc.
I have no respect for the judgment of libertarians and other Never Trumpers who even now, after all the good things that Trump has done, can't admit that they were wrong.
