Needles in Haystacks
A needle in a haystack is the paradigm example of something extremely hard to find. That's basically the job description of a CSI. So, how would the CSI: Miami team find a needle in a haystack?
Calleigh: Shoot the haystack, listen for the ping of a bullet hitting the needle.
Eric: Throw entire haystack into large body of water, wait for the hay to float away, go diving for the needle.
Natalia: Call in the FBI, tell them the needle might have some incriminating evidence against the lab.
Ryan: Leak to the media that there's a needle in the haystack, vaguely imply that it might be gold, step aside while the citizens of Miami converge on the haystack and tear it apart.
Alexx: Dissect the haystack with surgical precision, all the while murmuring to it comfortingly.
Horatio: Blow up the haystack.
These are just some of many possible solutions. I bet you can come up with some better ones. Please feel free to include them in a review.
