When “one side knows courtroom procedure” (the prosecutor), while the person who is falsely accused of a crime (the Defendant) does not, often the person who is falsely accused becomes victim to what is known as a color of law crime. We call typical scenarios like these where innocent people get put away a type of “Courtroom Abuse”.
Another type of “courtroom abuse” is when a civilian, who has not commit a crime nor given probable cause for an officer to suspect such, is shot & killed by an officer. Then the state chooses not to hold the officer accountable. This often leads to public outrage including protests, causing the situation to thereby escalate, endangering both officers and civilians!
