Blood Road: The Blood Road (Norwegian: "Blodveien" ) is a route northeast of Rognan in the municipality of Saltdal in Nordland county, Norway that was built by prisoners during the Second World War.  The route was a new section of Norwegian National Road 50 between Rognan and Langset on the east side of Saltdal Fjord ("Saltdalsfjorden"), where there was a ferry service before the war.

Eyewitness testimony: Eyewitness testimony is the account a bystander or victim gives in the courtroom, describing what that person observed that occurred during the specific incident under investigation.  Ideally this recollection of events is detailed; however, this is not always the case.  This recollection is used as evidence to show what happened from a witness' point of view.  Memory recall has been considered a credible source in the past, but has recently come under attack as forensics can now support psychologists in their claim that memories and individual perceptions can be unreliable, manipulated, and biased.  Due to this, many countries and states within the US are now attempting to make changes in how eyewitness testimony is presented in court.  Eyewitness testimony is a specialized focus within cognitive psychology.
