If they do find personally identifiable info in the bag don’t be too quick to blame that person. I know of a case in my home town where some people, who were in the middle of a dispute with others, placed their garbage on the front curb in anticipation of the garbage truck. The people they were feuding with (of course this is an assumption, it could have been anybody) grabbed one of the bags and promptly deposited it elsewhere hoping to get the owners in trouble. Just a thought.
