The police around Cedar Hill, DeSoto and Duncanville Texas have a fancy new communications system that broadcasts their 10-4s and 187s up to 30 miles, which coincidentally enough is screwing up a fancy radio-controlled networked sprinkler system in that general area. Turning off the sprinklers may not sound like it does anything except for making the grass die, but that's exactly what local residents are pissed off about—pissed off enough to get the FCC involved. Too bad for residents that the precedent for FCC decisions on cases where two frequencies overlap is to award use to public safety. If they don't, those same residents would be enjoying that fresh, green lawn when they're burning to death. [Dallas News]
