Factual error: Right after Kyle saws off the barrel of the shotgun in the alley, he pumps a shell into it, then again after his dream of the future in the car, then a 3rd time in the night club before he shoots the terminator. The 2nd and 3rd time he pumps it, shells should come out. They don't.
Factual error: Sarah and Lieutenant Traxler both state that Tech Noir, the club Sarah is in, is on Pico Boulevard. After the gun battle inside the club, Sarah leaves with Kyle and they run a short distance down the alley behind the club before getting into a car. The Terminator jumps on and falls off as soon as the car is out of the alley. When the cop calls it in, though, he says he needs an ambulance at 7th and Broadway. Even assuming Tech Noir was on the corner of Pico and Broadway, that is still about 3/4 of a mile away from 7th and Broadway, so there is no way that was the intersection just outside the alley.
