If a person is against the Jan 6 investigation, they are against orderly law, justice and democracy
At this point it becomes clear to any rational person would be for the investigation unless they were involved or thought they stood to profit from the downfall of democracy. At this point anyone against the investigation is a traitor to the United States of America.
Plain and simple, if they took someone on a tour, and they were a patriot, they would be giving all the details right up front and asking for justice. If they gave someone information, they would be saying oops, I messed up and informing the Jan 6 investigation and supporting the Jan 6 investigation. They would be angry at the people who betrayed their trust and their country if they had an ounce of patriotism.
Every time they speak against the investigation, they reveal what they are. They are not loyal to the Constitution or the country. They are loyal to an Oligarchy that needs to be brought up to charges of insurrection.
