We must pass laws mandating adequate funding for the judiciary, and mandating that after the prosecution's total expenditures surpass $50,000, the prosecution must contribute the amount it spends on its own expenses, minus the first $50,000, to a legal defense fund for the defendant.
This will ensure the government will not resort to dirty tactics like inundation with discovery materials, since they will just have to pay for the defendant's lawyers to read them all. They will not be able to subjugate defendants with their might, because defendants will have the means available to them to stand up to it.
Besides, the DoJ consumes an absurdly low proportion of the Federal budget [1]. Even if this law doubled the DoJ's budget (impossible; they still have to pay for facilities, support staff, etc.), it is a worthy price to pay for a safeguard of the liberties we've enjoyed for nearly a millennia.
1: http://www.justice.gov/ag/annualreports/pr2012/section3.pdf#... -- page III-18. Total appropriations received: ~$27 billion, $18 billion of which went to supporting the goal, "Prevent Crime, Protect the Rights of the American People, and Enforce Federal Law". The total of Federal expenditures for FY12 was $3,538.3 billion (http://www.fms.treas.gov/annualreport/cs2012/finhigh.pdf).
--> Current world: Defendants have a choice between accepting a certain jail term of Y or risking trial where they'll get in a range from 0-X (where X >> Y).
--> Your world: Defendants must risk trial where they'll get in a range from 0-X.
How is the second one better? If you want to reduce X, then just reduce X. The same argument goes if you say that Y must be some fraction of X --- if I were a defendant, I'd want at least an option of a very small Y (and if X is too high, just reduce X).
In addition to all the efficiency arguments (jurors, court costs, etc), guilty pleas save victims and witnesses from having to show up in court, be aggressively cross-examined by defense counsel, and suffer again. Why is it beneficial for somebody who knows he's guilty and knows he'll be convicted to have to inflict pain on his victims again?
[Edit: replied to wrong post]
In cases like this, offering a low-ball plea bargain (e.g. '6 month sentence or go to trial and risk 35 years') can mean that the prosecutor's office would rather not go to trial (because they have a weak case). Seems to me that if the case is weak, then prosecutor shouldn't be pursuing it.
[Though, maybe if it's a case of significant loss to the victim (e.g. murder), then pursuing the case even when it's weak may make sense.]
Though he gets bankrupted from legal costs either way for sure
From my own experience: in mental committment proceedings, there is no halfway point between letting the defendant stay free and committing them to a mental hospital. Consequently, the prosecutor's office simply never negotiates; they take every case to trial.
He didn't say that and I hope you know the difference. Reform is desperately needed.
Beyond that, one could argue that the federal government should not be addressing petty crime at all.
