When the Seattle PD Incident Report of Leah's arrest is shown at about 30 minutes in, it has various mistakes: her SS# has only 3 digits on the end instead of 4; her home phone and work phone are the same except for the first 2 numbers of the last 4 being reversed; and Cindy Busby is closer to 5'6 than 5'9 tall.
When Leah is in Valerie/Kathy's home and opens the package, the T-shirt reads "Favourite Mom" Since the movie is set in Seattle, they should have used the American spelling: "favorite."
