It has been fascinating to follow the Boston investigation. I am impressed by how quickly they mobilized their very large investigation team seeking all of the video resources that they could.
This is an article that describes how high tech video analysis is used to investigate crime. We are fortunate to have a video analysis system similar to what is being used here and two trained analyists. They have worked on cases for us and cases for police all around the region. Video evidence is incredibly important and the first place officers go after a serious crime is to locate video from the businesses around the location of the crime.
