Continuity mistake: When Wayne, Garth, Cassandra and Benjamin are at Benjamin's apartment, The level of Cassandra's champagne when she is standing out on the balcony is low. Cassandra then walks inside and sits on the sofa, where the level of champagne in her glass is higher, without anyone giving her a refill. (this is from a video viewing)
Continuity mistake: In the scene where Wayne and Cassandra are driving to the music store to buy the guitar, Cassandra crosses her legs in the car and you can see that they are bare. When they get to the shop, she is wearing pants.
Continuity mistake: When Wayne and Cassandra are driving together, Wayne's hands are at the 10 and 2 positions on the steering wheel, visible over the dashboard. However, the views from the driver's view out the windshield do not show Wayne's hands on the wheel.
Continuity mistake: When Garth is holding the air ratchet gun, he's facing to the left. However every time the camera shot goes back to Wayne, Garth is in the background instantly facing the car. Then when it cuts back to Garth, he's turned 90 degrees again.
Answer: You presumably haven't seen Terminator 2. The actor playing the cop is Robert Patrick, who played the shape-shifting T-1000 in that movie, who masqueraded as a policeman for most of the film. The T-1000's mission was to track down and terminate a boy - hence the "have you seen this boy" line that he says to Wayne.
