From BroadSnark:

When I was on grand jury duty we were told again and again that we were not to think about the consequences. When people asked what the possible punishment could be – because they clearly did not think the person should go to prison – the prosecutors would refuse to answer. When people had questions about the legality of searches, the prosecutors would tell us that the defense attorney would worry about that. When people asked questions about the flimsy evidence, the prosecutors told them that those matters would get settled at trial – knowing full well the case would never go to trial.

. . . On my better days I tried to focus on just how hard the system works to keep us compartmentalized. Without compartmentalization, the whole system would fail. As obedient as the people in that grand jury room were, had they had the opportunity to determine the actual consequences, I believe many of them would have refused to send people to prison. And I say that knowing that they were almost completely unaware of what happens in those places.

Our lives are entirely compartmentalized. We are pressured to limit our thinking all the time. We study in silos of academic disciplines. We work in factories or offices where we have little idea where our tasks fit into the whole. We draw lines through our work and personal lives so that the filth we do to earn a living might not dirty the rest of our lives. We allow ourselves to be cogs in oppression machines.

We have to stop compartmentalizing. We have to stop taking the easy road of choosing to follow orders because resisting is hard. It isn't o.k. to just go along.

You really should read the whole thing.

This may also be of some relevance to this; and also to this; and, strategically, to this.
