Goofs

When Katherine arrives on the stage, she puts down a backpack. During her final note, we get a back shot of the piano and the backpack is no where to be seen.

After the meeting between Emily and Ruth at the park bench, Emily is wearing white shoes. At the next shot where she's walking down the street (and being followed by Steve), her shoes swaps to black ones.

Katherine's hair during her final rehearsal performance- there are two tendrils loose, yet during some close ups, it's behind her ears. There's no way she would take her hands off the keys to fix her hair.

At 1:38'20": Ruth is on her hands then directly on her elbows on the next consecutive shot.

When the school bus pulls up and stops to board students, the stop sign on the side of the bus remains folded against the bus and there are no flashing lights on. Whenever a school bus stops to pick up or drop off passengers, the stop signs on either side of the will pop out with flashing lights to signal all vehicular traffic to stop and wait.

The Black SUV for Washington State Department of Corrections, and the Kitsap County Sheriff Patrol Car have the wrong Washington State Government License Plates.

All vehicles owned by any governmental agency in Washington State have exempt license plates, beginning with a vertical XMT followed by five numbers ending with a letter. That letter indicated the type of agency that owns that vehicle. Both the DOC SUV and the Sheriff Patrol Car have license plates ending with the letter "D". In Washington State the letter "D" indicates these vehicles are owned by a city agency.

The Sheriff Patrol Car should end with the letter "C", as the "C" indicates it's owned by a county agency.

The DOC SUV should end with the letter "E", as the "E" indicates it's owned by a state agency.

At exactly 53:46", Cross's mouth is late when he is heard saying the word "now".

If kate was 5 and the shooting happened 20 years ago mate would have been 25 not under her parents control.
