As I understand it, it's because the penalty for impeachment is removal from office, and possibly disbarment from holding the office in the future. There are no criminal penalties for impeachment. In essence, impeachment is an elaborate firing, for cause. An official gets impeached for failing to do their job or for failing to uphold their oath of office, which of course could include anything that would also get them arrested.
Impeachment does imply actual crime, however, per the constitution. What we witnessed was a bill of attainder. With a few bits of falsified evidence by the prosecution (dates, doctoring evidence submitted). And the basis for impeachment was for actions that were not violation of law.
It was a complete joke and it got the outcome one might expect.
If Trump sees legal consequences, it won't be over anything to do with the capital riot.
No, no actual law has to be broken to be impeached. "High crimes and misdemeanors" is non specific
???
What is your operating definition for the terms "high crime" and "misdemeanor"? The former is objectively a violation of actual law. If your standard for "misdemeanor" in the context of impeachment doesn't require a law to be broken, you don't have a standard for impeachment.
Now if the president does commit and actual crime, he apparently can be prosecuted later for that crime in a criminal or civil court.
This, however, is correct. Though it's an unsettled legal question to what extent a president (while still president) could pardon himself.
Then hopefully Trump faces a charge in court for fomenting rebellion, or sedition, if not outright treason. Something has to stick.
Not a chance in hell. Consider the case history on this and it would be a massive break in precedent. They'd be much better off going after him for taxes or something similar. Though I'm not a fan of "find me a man and I'll find you a crime" type conduct.
I think the most likely winners are GA election tampering and NY corruption.
GA election tampering would be interesting. If Trump's money is where his mouth is (in the figurative sense), he would welcome this because it would open the entire GA election process to discovery and forcibly grant him the platform the courts refused. I would be surprised if anybody were willing to bring that or NY corruption to court. Trump might be guilty in those or he might not be, and I don't know to what extent. But I suspect a lot of folks surrounding those want nothing to do with the legal process of discovery and the resulting publicity that would bring.
Simple analogy: if an employee murders a customer, they are likely to get fired and tried under criminal law.
That's not a useful analogy in this context. As a simple fact of law the actions Trump took leading up to the riot factually don't align with the allegations made in the impeachment.
Presumably, an employee accused of murder who actually just said "I hate these types of players in Call of Duty and wish they would die" who then got fired on the basis of him committing murder would have a case against both the firing and the false allegation.
