At the beginning of the program, the neighbor notices two suspicious people entering a home where the occupants are on vacation. When the police dispatcher asks for a unit to respond to a "211" (an armed robbery) in progress, the dispatcher should have said a "459" (a burglary) in progress. You burgle a location, but you rob a person. The female suspect only became armed (with a handgun) when she found one INSIDE the residence.
As Starksy grapples with the burglar in the house just after Hutch is shot, slamming him against the wall of the living room, it visibly wobbles under the pressure.
