I'm glad you're open to the possibility of earning trust anew.
The search was indeed unprecedented. A huge line crossed. I was quite surprised to learn DOJ sent agents to search Trump's home.
I view the search and the leaks as separate. The search was legal. DOJ, knowing the actions would be world-rocking and subject them to intense scrutiny, took steps to make sure everything they did passed muster. But the leaks -- people speaking off the record or without being named -- is bad. Such leaks strain credulity among skeptical readers and contribute to the negative bias toward the news outlets who do such reporting. More harmful is how such leaks undermine the dignity and authority of DOJ. I hate leaks. They do more harm than good.
I understand how they happen. When my wife and I were politically involved at a high level, it frequently happened that reporters or plants from the opposite side of whatever we were advocating at the time would flatter us, warm up to us, become increasingly acquainted with us, etc. They did it to get us to drop our guard and let info out that would not otherwise be known. These people are very good at that game. They know how to play on a person's ego and win their trust.
The other kind of leak is the intentional one where someone on staff is "not authorized to discuss ..." but is somehow intentionally sent to the press to get something out there that cannot otherwise be properly announced, or may be leaked for strategic reasons. I hate those kind of leaks too. It's hard to verify if (1) the leak is intentional, (2) the leak is accidental, made by someone who is careless with info that should be kept to one's self, or (3) false, made up by a reporter and represented as a leak because this bad-faith reporter wants to make news or have an impact of some sort.
None of them are good. I hate leaks.
You are not 100% wrong on that but not 100% right either.
Remember the Matt Gaetz news of his alleged sex with minors? Nothing came of that and if they were going to charge him, they would have done so by now, I would think. I don't like that guy at all but what happened to him was grossly unfair and unsubstantiated.
Some of the stuff said about Trump may be of the same ilk. But three grand juries are now conducting probes into Trump's conduct and legitimate investigations are underway. Charges may well result from one or more of these. And I agree with what you say; "... if Trump did something wring, fine. Charge him and try the case in court."
