@SW-User Well then, first and foremost I recommend you educate yourself on recent history and not rely on the culture du jour to tell you what to think and believe...
Should the FBI have left him alone simply because he was the president?
No, however if it turns out that recent Presidents such as Obama, Clinton and Bush Jr were given a wide latitude on what "archives" they took from the White House after they concluded their administrations then I would say Trump and his supporters have a point.
Also, has this illegal laptop thing run its course?
It has not, in fact new revelations come out all the time on this. Were you aware of the conspiracy amongst the major news networks and tech companies to claim this laptop was not legitimate and the result of "Russian disinformation"?
Have you reviewed some of the things found on this laptop? If not, what is stopping you? If so, do you believe it's fine to move on and not investigate some of this? It's clear he was heavily involved in drugs, prostitution, and possibly underage sex abuse, you think these things should just go unchallenged?
Has there been an investigation? Has it been concluded?
None that I am aware of. The Senate did a very brief investigation into specifically whether or not the laptop showed undo influence in Ukraine and China. They decided that it did, but not enough to warrant charges. Was that a political decision? I'd say it was.
