I think they even catch a stationary jammer once and awhile.
Going to figure the FCC would never catch someone who stuffed a portable battery unit into their purse and flipped it on at the local Multiplex and flipped it off when the movie ended. (Does not change it from being criminal of course, Just that operation to response time would be greater than the length of a film.)
Sad thing is I bet the FCC that we know today would respond to someone seeing boobs on Network TV first and then look into their actual job of protecting the radio spectrum in the US. -- [65 Arcanist]Filan(High Elf) Zone: Broadband Reports
