[Men in Black] Who is most important person that a Neuralyzer has ever been used on?

Probably some government officials. K said that the MIB separated from the government because they asked too many questions, which makes it reasonable to assume they were neuralyzed. 

Also, in MIB 2, they neuralyzed all of NYC which has some pretty important people in it.
