When Dalton's elevator rises from the sidewalk, the curb does not slope down to meet the street. When Dalton's motorcycle approaches the elevator, the curb now has a slope in it.
At the club, when Dalton, Shadow & MacGyver are surprised by the rogue CIA agents, the package under Dalton's arm disappears between shots.
Two cop cars follow Dalton and MacGyver down the mountain after they take off from where the dead body is found. A Dodge leaves first, then a minute or so later a Chevy Caprice follows. At the bottom of the road though, the Chevy arrives first, followed shortly by the Dodge.
When the two goons pull up to the funeral home, they park directly behind MacGyver's Jeep alongside a full curb. After Dalton and MacGyver escape on the motorcycle, the two bad guys jump in their car to follow. When they pull away from the curb, they drive straight ahead and would have collided with the Jeep except the Jeep has disappeared. The curb is also now sloped and there is a red painted "no parking" curb behind their car that wasn't there when they parked.
When Shadow, Jack and Mac are hanging from the garbage trucks gate, you can briefly see a crew member using a shovel to push trash out the back of the truck.
When MacGyver and Dalton stop to see Jack's contact dead, one of the police officers, an undercover bad guy, says they're the ones who killed the contact and then calls them by name: Dalton and MacGyver. Yet while he had seen MacGyver earlier in the episode, he had not heard his name and therefore would not know it.
