Drunk Driving Billboards Are Meant to Instill Fear

Here is a DUI billboard which is appearing right now in Austin, Texas.  The stated goal of the NHTSA (drunk driver detection) training that police officers undergo is to instill fear of arrest in the public.  Is it a good idea to make every citizen fear the police?  What kind of impact does this have on law enforcement?  It is the position of Charles M. Rowland that people who live in a free country should not be intimidated by their police force.  Further, the cause of eliminating impaired drivers is hurt when there is a wide-spread perception that officers are going to arrest no matter what.  Drunk driving is bad judgment at best, and tragic at worst, but does that mean that we establish a “police-state” mentality in order to deal with the problem?
