I was called up for jury selection in Manhattan, and this was my experience. They asked if anyone had a problem with the law in question (it was a drug case) and then asked if I would be able to return a guilty verdict.
I was not paneled on the jury. In my case, a large number (>100) jurors were dismissed for what did not appear to be any reason, so it may have been something else I said or something I wrote on the questionnaire they gave us. I was also surprised by the number of dismissed jurors, since I was led to believe (mostly, I think, by Law & Order) that there was a limit on the peremptory dismissals.
On the elevator on the way out, other dismissed jurors congratulated my on a novel way to avoid jury duty. This annoyed me, since I would have really liked to have been on that jury. Although I agree with the article that juries should have more powerful, I don't see how a believer in nullification can get on a jury without lying.
