You have no idea what it is like in life. You have a guess but it is entirly wrong.
But I do. Simply put I've been there, and no there not hundreds of leads. The people you 'torture' are not random guys, They were linked to the case in question. And the information they give is always always somthing you know and something new, They of course don't know which is which. Otherwise the information is usless and you will need endless amount of time and money to sort it.
Again. Your ideas about real life are entirely wrong.
