If you go to the county database, you can look up my name and my husband's and see if we owe any taxes. It's a matter of public record if you have a mortgage, and how much you owe. So should the public know who's on welfare and what they're buying at the grocery store?
Apparently several states including New York have released this information to the public. I can't imagine that some of these welfare recipients are using their money wisely at strip clubs and liquor shops, but there you go. Iowa is blocking the release of this information, claiming that the state only has an interest in determining who is eligible, not where they buy their goods and what those particular goods are. And they're not going to pass that info on to you.
Should you get to find out if a neighbour is taking state money?
