I'd say it at least approaches that one way street, as the word nullification implies a choice to not apply law despite factual basis for doing so. If there was to be a phrase for the opposite situation, in which a jury convicts because it simply wants to, despite lack of factual basis, I suppose maybe prejudiced juries is the phrase? There has been plenty of that in our history as well, certainly- but the deck is stacked against it purposely by requiring unanimity to convict, while any one juror may block a conviction. Jurors ideally should be represented from a good array of income, age, gender, and ethnic demographics, as presumably at least, a jury of very monolithic make-up would be more prone to vote together prejudicially. I do get the feeling that juries in general here tend to run more white, more aged, more midscale economically, and more female than the general population of adults in my area. But that's just a feeling, I can't produce studies to back it up, I do wish they existed.
I would like to see jury pools get greater representation from groups more disenfranchised from society. Juries comprised mostly of those who've done well in a big gov't atmosphere would tend to run more big gov't-friendly in my opinion, and be disinclined to nullify as frequently.
