You're not current on what used to be our judicial system. It's standard practice for prosecution and defense to negotiate plea deals to avoid jury trials while presumption of innocence is a shared joke between lawyers. The accused are worn down with extended incarceration while their careers are lost and families suffer on the outside. It almost always comes down to accepting a deal's lesser sentence regardless of guilt or innocence. Judges aren't kind to people who reject the game and lose their case in trial - most judges being former lawyers themselves.
These protesters were ushered in by the Capitol Police, pursued and rounded up by the compromised FBI using technical means strictly allowed only for terrorists, disallowed access to video evidence for their cases, held in conditions substandard even for murderers while overseen by a cruel guard force mostly made up of Democrat-following immigrants, held on minor charges yet denied possibility of bail - so yes many of these political prisoners will plead guilty to make the horror stop...or at least get a date in the future when it will. Real criminals are treated far better and aren't denied their rights.
A lot of broken windows, pummeled doors, rushed barricades, tear gas sprayed and other defensive actions taken if they were being led in.
Additionally I am quite aware of the push to plea bargain I nstead of eating up court time. But the defendant has the right to accept or reject the “deal”, if they want a jury trial should they take it to trial and they can’t be imprisoned for more time than stated in the statute. If found guilty, they risk being punished at the high end of the punishment scale. If they have accepted something premised on a “lie” and standing before a court admitting to it they are fools and worse liars.
Thanks for the quick synopsis.
