...Rachel Cooke is missing like so many other missing in this forum and across our country. Robert Cooke is doing everything he possibly can to bring Rachel home and to help other missing children.

Please help me understand...
This is a portion of news article on a post from the Laci Peterson forum.

"..Terry Fleck, a dog handler who has contracted with various Tahoe-area law enforcement agencies for 20 years, said dogs could track a scent even if Laci Peterson was in a moving vehicle, such as a boat trailer attached to a pickup.

"Scent percolates off of a person and drops to the ground," Fleck said. "You don't necessarily have to walk the route."

Teams of dogs can track over long distances by "leapfrogging" -- where one dog goes miles ahead on the last known trajectory and tries to pick up the scent, Fleck said.

"As long as the scent is available to the dog," Fleck said, "they can work it."

What I don't understand is why if Fleck is so right then why can't all of our missing children be found ?

Rachel, like so many other missing children was jogging, some of the missing kids were riding their bikes, while others were walking their dogs, or walking to/from school and their dorms etc. Why can't LE use the same methods to find these kids ??? I know LE does use K-9 so why not find the kids?
