As a programmer/contractor for DHS, I'd love to hear what you all think would be a useful set of APIs for DHS to make public. It's all fine and dandy to say 'oh yeah we have an API' but it needs to be something useful. So what would you want to see? Financial/Budget type data? Performance metrics across the different Components within the Department? What?
How about TSA budget, # of TSA employees, # of terror plots stopped, some ratios between those things, # of nail clippers confiscated per employee, etc.
