The President isn't above the law, but let's be real, the power vested in them means for the time they hold the office it's unreasonable and unrealistic to think their legal status should be the same as a common citizen. That period of their life should remain encapsulated as outside the bounds of typical prosecution. (Typical not meaning "any" but, like I said, if he's fucked up bad enough, impeach him, and if you can't, then too bad, you lose the chance). No President should have to live under the constant shadow of endless and purely political post-office revenge prosecutions when they're just back to being a "regular" guy.
Look at what they did to Trump WHILE in office with the impeachment farce, a duly elected President they don't like who they lacked the political capital to stop? Solution: throw him out with only a flimsy legal justification that is turning out to have been built on lies anyway, Tell me removing the existing unofficial post-office protections would not cause Banana Republic-level chaos like that to continue forever.
Every President would not only be permanently embattled while in office, but likely making decisions based not on the needs of the Republic but on appeasing those who are already plotting to be waiting outside the White House on inauguration day to slap the cuffs on him for rinky-dink charges that exist only to make him miserable in perpetuity after his term(S) for keeping them out of power for the last 4/8 years....
