The government has gamified the justice system: if you win (get more convictions) you will be promoted.
You will not be rewarded for putting guilty people in jail and letting go of the innocent, you simply have to do your best to score as many convictions as possible and anything you do to achieve this (intimidation, parallel construction, playing mind games and so on) is fair game. Guilt or lack thereof does not enter into the game.
I don't think it's fair to say the government has gamified the justice system. In most American jurisdictions, district attorneys are elected and so are state attorneys general. Candidates for such office aim to give the electorate what it wants, and it often seems as if the electorate wants prosecutors to be tough on the guilty to a far greater degree than it wants to protect the rights of the innocent.
You could run for DA on a platform of safeguarding the rights of criminal defendants and prosecutorial restraint, but that's not a winning platform in most jurisdictions except very liberal places. As long as we keep electing DAs (and in many jurisdictions, judges, albeit to a lesser extent), most of them are going to go for the lowest-common-denominator platform of promising to bring crime down and throwing the book at defendants.
