If forced into this false dichotomy, I'd choose freedom. Then again, the hospital I volunteer at just got shot up yesterday and boy would I have liked for that -not- to happen, and if that meant more checkpoints, I'd have to say, "So bet it."
Almost everyone in a first world country I've heard answer this chooses freedom in principle. Almost everyone I've heard answer a question like this it in a third world country said security.
Basically, it amounted to how scared people really were of being dragged into the streets and how hungry they were. Principles are very easy to abandon when danger goes from abstract to real. Everyone says they wouldn't give up their rights if there was a real cost to keeping them, but that is before they are tested. When things actually go bad, then you'll see who will compromise.
