Visible crew/equipment: When Robocop is riding in his patrol car just before the "Mom and pop" store robbery, if you watch closely as the camera is behind the cage in the car. You can see a camera man's silhouette in the lower right corner enjoying the ride. (00:33:45)
Continuity mistake: The bullet holes on Robocop in the convenience store appear /disappear between shots. (00:35:05)
Factual error: After Robocop stops the criminal from robbing the convenience store by bending his machine gun, the robber tries to run past him, only to get clotheslined by Robocop. The direction the robber flies after getting hit defies all physics. (00:35:15)
Visible crew/equipment: When RoboCop is going to the mayors office to stop Miller you can see the camera shadow on the reporters, just after he gets out of the car, and on the police lieutenant when he asks him "What the hell do you think you are doing?". (00:36:58)
Continuity mistake: When the guy holding the mayor hostage gets thrown out of the window, we see the only two TV cameras near the location follow his fall down to the ground. A few seconds later on the news though, the footage is the same shot we saw in the film, staying focused on the window. (00:39:55)
Continuity mistake: When the official is blown out of the window of City Hall, he falls out of screen. During the replay of the scene for the news immediately afterwards, the stunt man's feet are seen popping up into view as he bounces on the padding and rolls to take the impact. (00:40:00)
Revealing mistake: When RoboCop is getting into his car after remembering about his former life, and breaking out of the police station, look at the bottom of the screen. You can see that Peter Weller is only wearing half of the RoboCop costume, his right leg comes into shot as he gets into the car. (00:46:40)
Continuity mistake: In the scene where Emil is robbing the Shell gas station, he puts the machine gun in his right hand. But when Robocop drives by and sees him from a distance, the guy has the gun in his left hand. When they cut back to the close-up again, it's in his right hand again. (00:49:35)
Continuity mistake: When Robocop looks up his old address, his house number is the 500's on Primrose Street, but when he drives by the sign on his street it says he is in the 3000's section. (00:54:15)
Visible crew/equipment: When RoboCop enters the rave party, you can see the shadow of the camera twice, once on dancers, the other on a wall with a neon light picture on it. (00:55:25)
Continuity mistake: When Clarence is in Bob's house killing him, he sets a grenade on the table. If you watch carefully after Clarence pulls the pin out of the grenade, the timer is actually facing towards Bob as it is set on the table. When Bob crawls over to it the numbers are facing towards the camera, so we can see it counting down. (00:58:33)
Continuity mistake: When Clarence sets down the grenade on the table, we can see that there is a glass to the left of the grenade. When the view changes so we can see the whole room the glass has moved to the right of the grenade, then when we see Bob reaching for the grenade, there is no glass on the table. (00:58:34)
Continuity mistake: When Bob is reaching for the grenade on the table, we can see that there is cocaine all over the table, when the camera view changes to Dick's face on the TV and back again to the table, it's clean. (00:58:48)
Continuity mistake: When Robocop is fighting Clarence Boddicker in the cocaine factory he throws Boddicker through a plate glass window. If you watch closely, you can see the window shatter about 1-2 seconds before he goes through it. (01:05:40)
Continuity mistake: The blood Clarence spits on Robocop's visor disappears after he gets thrown through the window. (01:05:40)
Continuity mistake: When Robocop playbacks his recording of Clarence Boddicker spilling his guts about Dick Jones, the words he says are different than the ones that were recorded. (01:06:25 - 01:09:05)
Visible crew/equipment: Robocop tries to arrest Dick Jones but fails, and an ED-209 is brought in to destroy Robocop. During their fight scene, it fires a missile at Robocop, and you can clearly see the guide-wire that the missiles fly along (especially in slo-mo). (01:09:00)
Visible crew/equipment: When Robocop tries to arrest Dick Jones, Robocop's system messes up. In the close shot of Robocop's helmet the whole film crew is visible. (01:10:10)
Continuity mistake: Dick Jones brags (admits?) to Robocop, "I had to kill Bob Morton because he made a mistake. Now, it's time to erase that mistake" while Robocop is crouched on the ground, not only looking away from him from across the room, but also Robocop's eyes are in a vertical position. In the playback, Jones is facing the camera as though it were videotaped or filmed in a studio. (01:10:50 - 01:35:10)
Continuity mistake: When Clarence is checking the RoboCop Locator in Dick's office, the little light that tells you where RoboCop is still flashes after Clarence turns the locator off. (01:16:16)
Answer: Because he knew he was doing illegal activities. Robocop was said to be highly efficient at his job and Jones did not want to risk him out on the streets without the insurance of shutting him down if Robo came after him.
