"Feel prejudicial," yes, that's exactly how it feels to me as well. I'd feel extremely uncomfortable if I were on the jury and had to answer the questionnaire; I'd worry about how my answers would be used and fear someone try to force me to provide names. Sort of the way the police/courts do now with purported drug dealers (which explains why actual drug dealers often receive short sentences while their friends and family members -- who are not dealing and have no information to trade -- receive much long prison terms).
