should justice be denied the innocentYou may not understand that 'justice' sometimes REQUIRES that the guilty go free. Until you understand and embrace that, you cannot understand liberty.
For example, a person commits a murder, and the only person who saw the crime is the suspect. According to the 5th amendment, the government connot coerce him into providing the convicting evidence against himself. He will go free.
Otherwise, you cannot imagine the horrors the govt can perpetrate on other innocents.
I don't understand justice and liberty? Tell that to two dead girls and their families why their murderers are walking the streets. They have suffered the ultimate horror in a very, very real sense and you want to talk about abstract concepts. No one is kicking in doors or rounding people up for interrogation in dank rooms. If they can eliminate the folks who didn't do the crime and focus on the people who are good suspects then maybe they get them. Otherwise, we can go back to frontier justice or rely upon the retaliatory drive by as a way to get justice with the hope that no other innocents get lynched or shot by mistake.
