Michigan State Representative Tim Kelly (R-Saginaw Township) has introduced a bill to repeal the state's Forensic Polygraph Examiners Act (http://www.legislature.mi.gov/%28S%28mhnekjnf3fl2iz45sw05f03i%29%29/mileg.aspx?page=getobject&objectname=mcl-Act-295-of-1972). Kelly's one-line bill would end the licensing and regulation of "persons who purport to be able to detect deception, verify truthfulness, or provide a diagnostic opinion of either through the use of any device or instrumentation as lie detectors, forensic polygraphs, deceptographs, emotional stress meters or similar or related devices and instruments."
I think this is a great idea. State licensing boards for polygraph examiners bestow an air of legitimacy on a practice that has none. Polygraphers should no more be licensed than tarot card readers.
I don't know the bill's prospects of passing, but one good sign is that its sponsor, Tim Kelly, has been named assistant whip (http://www.mlive.com/news/saginaw/index.ssf/2013/02/saginaw_township_state_rep_tim.html) for the current legislative session. He should know how to count and round up votes.
