== Chemical Test == 

 I'm new to wiki but it bothered me greatly that the text implied that a US law enforcement officer would "take" or "force" a blood sample from a person. 

 I did my best to clarify that it requires a search warrant issued be a criminal magistrate. Further only medical personal such as a RN are allowed to draw the blood. 

 As a LEO that has investigated a dozen DUI cases I think its important that people understand that any search of a persons blood will require a warrant issued only by giving in person testimony to the probable cause before a neutral judicial official.
