Plot hole: Laurie calls the police from 1987 Winchester drive, and gives them that address. Yet the police responding to the call go directly to 1960 Winchester drive - where Laurie has run to and is now hiding - even though it's on the other side of the street and several houses down. (01:31:30 - 01:33:40)
Suggested correction: Initially Laurie sends Lindsay across the street, back to the Doyle house to call the police. It's possible Lindsay gave the police the Doyle's address (since that's where she was calling from). Since that call was likely made before Laurie made her call, that explains why the police first show up to the Doyle's house (responding to Lindsay's call) and Bracket shows up minutes later at the Wallace's house (responding to Laurie's call).
