The LAPD, The FBI, and The CIA all are best to catch criminal.
One day the President wants to give them a test and he releases a rabbit into a forest and each of them has to catch it. The LAPD, The FBI, and The CIA all are trying to prove that they are the best.
The CIA proceeds in.
They set animal informants throughout the forest. They question all plant and mineral witnesses about the rabbi. After two months of extensive investigations they conclude that rabbits do not exist in that forest.
Then The FBI goes in.
After two weeks with no leads they burn the forest, killing everything in it, including the rabbit, and they make no apologies for that.
Finally The LAPD goes in.
They come out two hours later with a badly beaten leopard. The leopard is yelling: "Okay! Okay! I'm a rabbit! I'm a rabbit!"
