Evidence?

[LRZ]

The recent "steal, foul, altercation" thread got me thinking about how we use these videos, run multiple times, in slow motion, to determine what we would rule in situations. But I wonder what would or could you use to determine what fouls to call on which players, bench personnel, coaches? In a game that doesn't have some official recording for review, can you use a video offered by someone from the stands? (For no other purpose but for a melee--e.g., not to determine if a last-second shot counts.)

Without video review, I'd have a hard time identifying everything that I perhaps should, especially as I only work 2-official NFHS games. But, on the other hand, I'd hesitate to rely on a recording made by a fan, even if it might seem to be objective and helpful.
