Doesn't that pretty much say that 22 years of experience is worthless? I would offer that reality should be recognized that when a hunch turns out to be on the money it is time to congratulate for a job well done rather than hide away the truth that was gained.
Nope, not at all. Unless you can prove that the cop in question has a long history of accurate hunches with no innaccurate ones. Otherwise, how can you prove that his hunch was correct or he just played the odds. ie, if you question 20 people on a hunch and find the goods on one, you're really just practicing illegal search and siezure and just waiting for the one time you get lucky and come across a guilty party.
