So the prosecution has months to prepare their case, and you (with your lawyer) are informed of the charges the day you show up in court? Kinda hard to build a defense on the spur of the moment.
And if the prosecution takes weeks or months to prepare their case, they will, undoubtedly, interview a lot of people. People the defendant knows. And when the defendant hears a case is being built, do you think he will just hang around and wait for the cops?
And the defendant can post bail. They don't have to sit and wait.
The police already interview people and the defendant already has a chance to flee.
Your lawyer would be provided a copy of every piece of evidence as it is being presented in court at the same time the judge and the jury sees it.
Additionally, if someone pleads innocent and is found guilty, the court is determining that they are lying and they would be automatically convicted of perjury on top of any other convictions.
Your defense lawyer gets to see every piece of evidence at the same time the judge and jury do? How the hell can your lawyer build a defense? This is just railroading people and calling it speeding up the trials.
Yes, the police interview people. But when they have the evidence, they make an arrest. What happens if, while the prosecution is building and airtight case, the criminals do it again and again? You want to let a murderer go free until the prosecution has their case built? Or a rapist?
And as for the perjury charge, unless you can actually prove they are lying, the fact that they were found guilty is not grounds for a perjury charge.
What you want is a very authoritarian gov't, with the odds stacked in favor of the prosecution by a mile. The prosecution gets as long as they want to build a case, but the defense shows up and see all the evidence at the time he has to defend you. No chance to investigate, bring in witnesses to refute the prosecution, or even verify the evidence is 100% accurate.
No. Not in this country, anyway.
