Shadows of Doubt is an incredible game, and I highly recommend it.

The snipers missing their shots is a pretty funny problem honestly, sounds more like it’s an issue with how they identify that they have a clear shot rather than an actual accuracy issue.

Also, part of how the game simulation works is that when one of the simulated people decides to commit murder, they have to acquire a weapon to do so. So if someone decides to kill as a sniper, they will either already need the gun/ammo for it, or they will seek out a black market dealer to buy from. However apparently once they’ve bought ammo, that ammo becomes unlimited, leading to the huge ammo piles when they can’t actually get a clear shot on their target.
