You think Trump is above investigations and the law? He is not.
Down goes the strawman! Nobody said he's above the law, nor did anyone say he was above investigation.
If there's reason to believe the President may be guilty of colluding with the Russian government, the intelligence community has an obligation to investigate as much as is legal and necessary. Going "to war" is acceptable if it stays within those boundaries, especially when the highest levels of national security and integrity are at stake. And while the leaks to the press are clearly strategic, silencing them wouldn't stop the investigation.
If there are legimitate things to investigate, then by all means, have at it, I have no problem with them investigating. If they have actual evidence of something, then fine, bring it forth. Undermining the president with BS leaks etc? Not so much. If you can't or won't serve under the president, then you should quit.
Moreover, you're conveniently glossing over why there's a desire to go to war. It's because Trump not only has open contempt for the intelligence community, but is setting up an administration designed to help him avoid accountability. Never mind the kiss-ass Congress -- we're talking about an attorney general who's reluctant to recuse himself from any involvement in the Flynn investigation, even though he's legally required to bow out. How do you hold possible traitors to account when the people controlling the oversight mechanisms will gladly block or interfere with investigations?
You're basically advocating a coup then by the intelligence community. As I said, such traitors should be executed. Preferably publicly to set the example.
I do think the NSA, CIA and other agencies overreach sometimes. But this is entirely within their scope -- it's their duty, even. If the President had the right to purge the intelligence community whenever it caught him breaking the law, we'd be living in a dictatorship, not a republic with checks and balances.
That's the whole point you're missing. There is no evidence ----- ZERO EVIDENCE -- that the president has done anything unlawful. Actively undermining the president simply because you disagree with him, his administration or his policies is not their role or duty. If there was actual evidence of wrongdoing, bring it forth, there are processes for that.
