Promoting a game like this would be an interesting way for China, Russia, NastyCorp, etc. (insert bad guy) to cultivate a network of HUMINT sources within the U.S. for low priority work. Create and run it as a game until you've got someone who lives near that scientist you want to keep tabs on:

"Welcome operative. Your neighbor at 2201 Main is also playing, and is your next target. To earn points, select from the missions below:

(500 points) For each day of the week of 2/24, call your handler at 212-555-1212 [twilio number] and report the time that the target returns home from work.

(1000 points) Your target has left an important clue in his trash. Rifle through his trash midday to find the clue. You will have to determine what it is. When you've found it, mail it to 2222 Anystreet."
