Police Use 3D Scanners To Capture Crime Scenes
Developments in 3D scanning have been top of technological news for quite some time now, and it is about time such developments were implemented into our day-to-day society.
The latest in 3D scanning technology comes from company Faro Technology. Their devices use various touch point markers, which allow the laser to bounce off a mirror, hitting an object and recording its position. This happens roughly 250,000 times per second and builds up a point cloud, creating an accurate representation of the scene in 3D. The laser measures every cubic inch and has an accuracy of +/- 2mm.
This technology, known as Focus3D, is now being used by the police to record all the information they need from a crime scene, allowing them to clear the scene quickly. This is brilliant news in the case of road crashes and accidents, as it means traffic will not be waiting so long while the accident scene is logged. Hopefully this means the end of hour-long queues on the motorway!
Although Focus3D is only currently being used nationwide by police for traffic accidents, the technology could be useful in a recording a range of crime scenes, from theft to murder. It could even be shown to juries, as it creates a more realistic and accurate representation than 2D designs. This would mean more reliable evidence for big trials and a greater understanding of the case by the jury.
However, there is a downside. Some critics have already expressed worries about use of these graphical representations. Focus3D scans can be manipulated to take measurements, or set markers of crime scene areas to aid police detectives. Yet this also means that the evidence itself could be manipulated as anyone who can access the scan would be able to alter it. What if scans fell into the wrong hands? Innocent people could be set up or not receive the justice they deserve. Or what if scans were leaked to the general public? That would make them unusable in court and could upset whole trials.
Personally I think it’s brilliant that the police have started to use Focus3D. In this modern age the police need to advance alongside technology to allow for accurate representations and judgement of crimes. As technology advances we should be able to gather more and more reliable evidence, and allow for greater understanding of each case. Therefore enabling us to charge those in the wrong, without fear of prosecuting an innocent passer-by or victim.
These worries of manipulation and leakage are indeed, worrying, but in this modern day and age virtually everything is at risk of a security breach. It is more important to advance our methods of crime scene investigation, alongside advancements of internet security, than to simply sit in a hole and hide from new technology out of fear.
