Of course I believe in the 4th Amendment. Insinuating I don’t is unhelpful to this conversation and to be honest, a bit insulting.
The intelligence community dos not just police itself and faces extensive oversight. There are many ways to report wrong doing without dumping hundreds of gigs of classified data on the internet. Everything from simply noting the concern to superiors, filing IG complaints, or even going direct to your member of Congress.
I have seen these internal processes work, they’re real and effective. Not always fast but they do eventually address issues.
No one was hunting Snowden until after he stole hard drives and got on a plane to freakin China. He didn’t even attempt to report his concerns to his superiors, internal compliance, IG channels, or even Congress.
He just decided on his own to steal classified info and flee to America’s most dangerous adversaries with it.
Now there was a legitimate concern with some of the NSA collection activities. Specifically bulk collection that included American citizen data. This happened not because the NSA was even trying to collect that but as a side effect.
If you need the Gmail data of a foreign target and you realize Google is using unencrypted HTTP to transfer data between data centers, then if you siphon that data you’ll find your target’s emails. Bonus, you’ll get all your other targets emails too.
The improper part comes in that you’ll also get millions of Americans data and at the time, no process to safe guard it from unauthorized access. This was a real problem addressed with new rules/regulations/processes.
This being leaked alerted many really bad people that the NSA was reading their email. So they changed TTP and went dark. Worse, most of what Snowden leaked had nothing to do with collecting American data.
Most of what he exposed was on going collection programs for terrorists and foreign governments. Remember Markel’s cell phone? Leaking that had nothing to do with the 4th Amendment.
Finally, I am not an intelligence professional. But I am a customer of intelligence production. I got a front row seat to many valuable sources of intel vanishing overnight because of his leaks. Again, I’m talking about intel collection on really bad folks and adversary militaries. Losing that access put Americans in danger and likely directly cost lives in Iraq and Afghanistan as terror groups changed communication methods post-leaks.
