Factual error: The gunpowder made in the 1950's didn't produce the clouds of smoke we see whenever the police fire their weapons, but those of the 1870's did. Ed must have nicked some ammo from the Lone Ranger's property master, eh?
Factual error: The cemetery is full of bare branches of medium to small 'plants'. Since this is southern California, they should have leaves.
