** Bogus argument. i'm not commenting on the judicial system as if I'm an expert. I'm saying from a high level perspective, all the factors you listed do not focus on the purpose of a justice system: Justice
Justice is not a science, it is not a paper target where you can tell whether you hit the bullseye. Is it justice if prosecutors takes a case that looks like justified self defense and charges it as a murder even though the will probably lose? Justice for the family of the dead person looks a lot different than justice for the person who was trying to defend himself.
** Prosecutors need to take viable cases to court, not just likely winnable ones. your argument that it would be a waste of time and money and an attempt to convict an innocent person is not a justification for only trying the ones you think you can win. All that's needed is enough evidence to convince a judge or jury the crime occurred and the accused did it. If a prosecutor is bringing charges with insufficient evidence to sustain the charges, then the judge has the right and duty to reprimand the prosecutor. Sometimes judges will dismiss cases from certain prosecutors based on a defense motion that the prosecution failed to meet their burden of proof, thereby saving the courts and the parties time and money. So, whining about time and money used for cases that might go either way is not a valid justification.
It isn't merely prosecutors wanting easy wins to make them look good. Now I am not saying that isn't ever a factor, a merit based system can create the incentive to juts take the easy wins. Again, in a triage system you have to pick the best ones that you think you can win because you could not physically take them all. It isn't a perfect system, god knows they make mistakes sometimes but it isn't the system you paint of lazy prosecutors only looking for easy wins. An experienced prosecutor knows what tends to work in court in front of a judge and a jury. For example whether a confession will be tossed out or admitted and the whole case hinges on the confession.
** Really? Most of the time? Where is your source for that assertion? You're trying to make an argument that has no actual cases as examples. i know for a fact if you get arrested (for example) for DUI, you are issued a summons after being arraigned. if you don't make that court date and don't bother to ask for a continuance, the judge has several options. An arrest warrant is only one option. Courts use bail, incarceration and monitored house arrest along with other measures to pressure defendants' to attend court.
I have no idea why judges don't bother to convict people for contempt when they don't show up for court, I assume it is because it would take time to prepare a prosecution and then a jury trial for everyone who demanded one. The main goal is to have the person back in court. No offense but I am not going to give you a source. Trust me or don't that's fine but next time you meet a cop try ask them how true that is in their experience.
From what I've seen, judges are more likely to dismiss the charges used for a missed court appearance unless it's habitual. My Ex was placed under a domestic order of protection (not against me -- against the co-worker she was living with after moving out). She violated the order and was arrested and charged with criminal contempt of court. That was NOT listed as a separate case, but rather another charge recorded under the original case. So most reports would not list missed court appearances as separate arrests.
No matter how many warrants you get, they are still part of the same case number, so it's not multiple arrests if you miss court 3 times for the same case. Now if you want to treat each charge as a separate arrest, that's different. In my world, actual charges a person is arrested for are more illustrative of the person's criminal character than the number of times they might have been arrested. That shows there was PC to make the arrest, even if the charges are dropped later. That would also list any bench warrant arrests like you're trying to quibble over.
If you skipped court 3 times on the same case that would be 3 separate warrants and 3 separate offenses for the purposes of counting the arrests even if those 3 are all stemming from the same initial case.
I would caution against arrests as a reliable indicator of PC that the person committed the crime in question. Now if someone has been arrested for theft 10 times there is no way I am believing they are all wrong but it is not that rare to have someone arrested for a crime where PC existed to justify the arrest but it turns out later that they didn't commit a crime (misidentification, misjudgment, false claims, etc)
