I propose that we collect this data on dogs when people register them, so that when the owners leave shit on the sidewalk they can be identified and burned at the stake.

It would maintain shit <--> dog <--> owner <--> known addresses gathered from public sources and have scout teams that find dogshit, identify its owner, and send it to them on a nice little package; perhaps one of the addresses is their workplace, which is so convenient. Or perhaps there can be an app for geotagging lost feces...
