I don't know the legal intricacies of this situation. I believe it is unprecedented and new legal arguments and theories will appear.
U.S. Grant was arrested for repeat offenses of speeding in his horse and buggy in DC but was not jailed. He had to walk back to the WH.

I do not like to think of Trump in a NYC jail without security including a food taster.
So what's the plan?
Trump is being indicated on state charges not federal. DeSantis will have to approuve an extradition I believe. I don't think he's that suicidal....
