> These are the most highly instumented areas of the planet. Just look at google maps of San Nicolas island off San Diego. A Navy range bristling with the most advanced electro-optical and radar sensors on earth.
The more highly-sophisticated equipment you have tracking one area, the more likely you are to get false readings in that area, assuming the equipment has any kind of failure rate.
For a comparison, LHC has "seen" many millions of much more impressive events, with much more sensitive equipment. They don't go publishing about new particles every day though, because they know how to account for measurement flukes in their instruments.
