All members of the military take an oath. It is done for a reason. It may seem hollow but it has a purpose. It allows for firing squads upon conviction of desertion or treason. Without the oath, such acts are not punishable by death.
I agree how hollow and disgusting can be the liar media’s self-exaltation as bastions of a free press.
But I would not compare that to the Oaths taken by those pledging their lives to the service of our country.
Where or how do you get that conclusion? A non-oath taking member of the general public who commits treason is exposed too.
Obviously some people take the oath seriously. I'm not belittling that. And of couse the oath is taken out, dusted off, and used to prop itself up, "you swore and oath and defiled it, to the gulag!" My point was on the net effect, spread across the millions of people who take the oath. It can and is used to justify hiding evidence - "trust me, I took an oath."
As for the comparison with the principle of an honest and public-serving press, that's my point of view. Maybe your local constabulary and bench are honest, maybe not. The difference is not determined by taking of the oath. No institution is beyond corruption, not even the pentagon.
