well unlike most, I believe there can be something to LRL. however,
I believe it is just an Extension of the Mind of the User.
in other words The user is most likely already very experienced on using his eyes & mind to see clues.
& the LRL just helps him free any deep thoughts , & brings them to the surface.
causing him to believe the LRL did it
I do believe we are all capable of being psychic if our minds are awakened
(anyone who thought about someone just before the phone rang & it was them,
Know what I mean)
(I know cue the twilight Zone Theme lol, not everyone's mind can be enlightened

)
any-Who ............
Samuel Tree claimed golf ball detectors could track down missing people if a photograph of them was placed inside
Now that's just too much, even for my Mind

& sorry but if Governments actually believed that and forked out tons of money...
they are the ones who should be on trial in my opinion.
they either need to prove they know something about Hocus-Pocus we don't
or take mental competency tests
