At least it can be analyzed by experts. No video at all means there is nothing to analyze. Experts aren't (necessarily) cheap and even then it's a crapshoot. I don't know that they've analysed the costs vs benefits of taking unsigned video correctly, but I'm pretty sure that they at least know some of the costs, so I suspect that they're closer than folks who think that there are no costs.
