Answer: being replaced by security and surveillance cameras
Step-by-step explanation:
Video is able to show more of how a crime was committed and so is preferred by courts when it comes to criminal and civil proceedings. Photographs on the other hand, can sometimes be taken out of context which can wrongfully implicate a person.
For this reason therefore, the courts are moving more towards video from security and surveillance cameras which has led to these devices being more widely available and used in the world. For instance, London has 691,000 security and surveillance cameras to enable easier crime detection and evidence gathering.
