Corrected entry: When Charlie's mother is in the hospital, Charlie puts up crosses all over the walls and windows, supposedly to keep Jerry away. However, this was after the scene where Charlie held up a cross to Jerry on the roadway and Jerry grabbed the cross and it caught fire. So, Charlie would have known that the crosses had no detrimental effect on Jerry.
Factual error: Jerry digs up a natural gas pipeline in the backyard and jerks it so hard that a pipe coupling in Charlie's house breaks, venting natural gas into the house for about 4 seconds. Then Jerry uses a cigarette lighter to send a flame through the pipeline, exploding Charlie's house like a fire bomb, catching virtually every room in the house on fire. In reality, it would take an hour or more for vented natural gas to accumulate sufficiently to blow up a house, for one thing. For another thing, Jerry broke the gas pipeline in the backyard in order to ignite it; so, while the broken pipeline leading to Charlie's house had no gas pressure, the pressurized side of the pipeline was still in the backyard with Jerry. Meaning, Jerry himself should have been engulfed in fire as soon as he sparked a flame.
Jerry Dandrige: Hey, guy. You've been watching me. I've been watching you. Your mom. There's a kind of neglect. Gives off a kind of scent. And your girl? She is ripe. It's on you to look out for them because there are a lot of bad people out there, Charlie.
