A sitting president cannot be arrested. He cannot be detained. The Department of Justice issued an opinion about this back in 1973, and reviewed that decision and updated it in 2000. The decision can be found here: http://www.justice.gov/olc/opiniondocs/op-olc-v024-p0222.pdf.
The basic finding:
“The indictment or criminal prosecution of a sitting President would unconstitutionally undermine the capacity of the executive branch to perform its constitutionally assigned functions.”
So, again, go back to the Constitution. The only way to remove a sitting President is through impeachment and conviction.
Quit pinning your hopes on a military coup.
The DOJ? The DOJ that is appointed by a POTUS said that a POTUS can never be arrested?
How convenient.
The DOJ is not in charge of the military so they can’t say what the military can or can’t do. (And just as an aside, has any court affirmed this DOJ opinion? DOJ opinions have been overturned many times when brought to a court)
“Indictment or criminal prosecution” is not the same thing as the detainment of an enemy combatant who may or may not ever be charged with an actual crime.
Answer me this: How would an impeachment ever stop an enemy POTUS from having his surrogates attack this country while the enemy DOJ and DHS are looking at naked pics of 90-year-old nuns and letting Saudi Arabian Wahhabists waltz through the airports with “preferred” status so they aren’t scrutinized at all - all before the Senate could even begin to collect evidence?
Impeachment is a pathetic joke, if the POTUS is really an enemy combatant. It’s like saying to protect itself from ISIS, the Iraq government could impeach ISIS - never arrest anybody in ISIS, never take away the ammunition, etc - just hope that ISIS complies and doesn’t destroy the country while the government piddles around with this joke of an “impeachment”.
If what you’re saying is correct, then the US has NO emergency brake and in fact, not even ANY brake, because the brake (impeachment) can only stop the car about 6 months after you press on it, while the car keeps going unhindered...
