Reasonable Suspicion, Probable Cause, and Field Sobriety Tests

A police officer requires “reasonable suspicion” to stop a vehicle and “probable cause” to place a person under arrest for DUI. In reality, however, officers stop and arrest drinking drivers on snap decisions. By using standardized forms and key phrases, however, officers can create compelling narratives to support the stop and arrest decision. These reports frequently appear cookie-cutter, but it passes muster in the courts. A motorist may be stopped for any number of reasons.

What is “forensic” science, and why does it make me feel icky whenever a prosecutor uses the word in DUI cases?

According to Webster’s Dictionary, “forensic” is defined as: Etymology: Latin forensis public, forensic, from forum forum 1 : belonging to, used in, or suitable to courts of judicature or to public discussion and debate 2 : argumentative, rhetorical 3 : relating to or dealing with the application of scientific knowledge to legal problems.
