Other mistake: Chucky cuts Andy's Achilles tendon from under his bed. Throughout the rest of the movie, Andy should have a limp from such a severe injury. However, he has no trouble walking or running in subsequent scenes, nor does he show any signs of injury.
Other mistake: During the breakfast scene, Sgt. Botnick tells Andy he needs a trim on Wednesday, but he had just given him a haircut the previous day.
Other mistake: When Charles is thrown away and gets dumped in the back of the garbage truck, he screams for the garbage man who hears him and jumps in. There's no way he could have heard Charles screaming or the cadets hear the garbage man screaming from the marching field. Front loaders are loud and nearly impossible to hear screaming even near the truck.
Answer: The public believes that the Good Guy doll that committed the murders had simply malfunctioned, which caused great negative publicity for the company. The public does not believe Andy or his mother's claims that the doll was possessed by a serial killer and was actually alive. In Child's Play 2 the company finds and reassembles the doll to prove to shareholders that the Good Guy doll is safe. This backfires and the doll is re-possessed, which leads to additional murders in that film crippling the company for 8 years.
