Follow a federal agent home from work and film them and their house. Film their children going to school and post pictures locations and times online, also taking photos of other relatives, friends etc and where they live and their phone numbers and post it all online.
Have your friends join in and keep posting every detail and picture you can get of federal agents and their families etc and compile it into a website.
Then let me know how that works out.
Edit: Does anyone know of any USA law that stands against such activity?
