What will the freegans do if we outlaw trash picking? Not to mention, I've found some awesome working computer parts (1000W ATX power units, with cool looking internal cables, fuck yeah!) and completely reasonable, non-branded, desktop chassis on the side of the road.

Surprising as it is that a blood test for drug use gleaned from one's bio-waste is slightly rotten, maybe it's the vice laws that should be thrown some shade. Fourth amendment, sure, but I think it's worth noting that it's still the burden of the individual to render their discarded waste non-incriminating.

What this means for genetic privacy, finger prints and other powerful personal identifiers (the what-you-are authentication factors), I simply don't have a good answer for.
