A view just out the front of the plane wouldn't do much to help crash investigations and one of the big reasons they don't is you have to make a large enough storage resilient enough it can reasonably survive a crash. Most crashes are no where near this gentle.
Far more useful would be an interior cockpit view showing the crew and the actions they were taking but a lot of that is recorded to the FDR on newer planes too.
True. A better external placement would be a wide angle tail-mounted camera that can film the entire aircraft from the rear. Some airlines (e.g. Emirates) already have this live view available on the infotainment.
