As Brogan and Weldon leave the station house with the spore, the power cord for the spore prop's lighting can be seen trailing from the bottom of the cannister.
The images of the devastated alien planet that Welden shows to Brogan are far too low to have been taken from a satellite.
Dorek Kyyster (played by Wayne Forester) is incorrectly litsed in the end credits as "Kyster".
Tendall Kalike (played by Andy Dawson) is incorrected credited at the end of the episode as "Kaliki".
So what happened with Carson? He is Slomo's mechanic, yet nothing came of Brogan finding the bugging device inside Slomo.
At the crime scene where the professor was murdered, the Tarn police officer that Brogan addresses as Selmar is missing the DCPD shoulder patch from the right arm of his jacket as he turns towards the dumpster.
Unless the bank vault's inner door was built to withstand sudden decompression and/or the vacuum of space, the top of the bank should've buckled tremendously.
Zan sprays his hand with some latex-y substance in order to get the handprint of the manager. This wouldn't work for two reasons:
Zan needed the fingerprint at the tip of the finger but the manager's fingers go across Zan's palm and around to the back of of his hand.
Zan places his latex "hand" on the monitor like he'd put his own hand but that would have the palm and fingerprints upside-down.
If Haldane doesn't believe in luck, as he told Castle in "The Witness", why does he tease Castle with his 'your lucky I still exist' statement?
Cancel the security card after the cops get around to thinking of it? The security company and/or armored car company would've looked to see who the team in the vehicle and rescind their security clearances for this very reason.
The company that employed them would know who was driving/riding in the stopped vehicle through their work schedules, and know who is dead that way. Yes, it would take time, but the way the episode plays out, Brogan gets the break with the card some time after the discovery of the armored car. The other company(ies) would've notified the families and rescinded anything sensitive either man had connected to him.
Brogan's home is shown to be "Apartment 9751", but the space station he lives on clearly only has room for about two dozen apartments, not nearly 10,000.
Sally works at the Demeter Memorial Hospital in this episosde but in all others, including "Illegal" and "Hate Street", she works at the Demeter City Hospital.
While Tarns and Creons may not have extremely sensitive senses, that Morgan was able to bluff Romek into blindly following him with a 'Didja hear that?!' seems sloppy. Romek may cut corners, but he's not so sloppy that a human could run that kind of bluff on him.
The shots of the Police cruiser docking bay feature a rare appearance of the Police patrol bike, which takes the form of an enlarged motorcycle with a tripod-like design and three large horizontal 'tyres'.
In Haldane's flashback to the chase, his and Brogan's cruiser has it's cannon's deployed as Castle manouvers between them and the getaway vehicle. However after Castle veers off, the cannons deploy again.
One of the convicts, played by Ray Winstone, has a different voice in some scenes (this is due to him being dubbed by Wayne Forester in some scenes, while others were left with Winstone's own voice).
While in his office discussing the take over on the Rock, Podly has to be reminded of Gagnon's former associates at the prison, yet he'd not long earlier had a conversation with Gagnon about those exact people and Gagnon's delight at being reunited with them.
As Houdini physically attacks the two convicts in the cruiser hanger bay, the rifle carried by the human convict can be seen to bounce at least several iches off the wall and later spins when kicked. This would suggest that the gun was extremely light, certainly not what you'd expect from such a weapon.
In the first scene, some of the people in the crowd react to Vinny's assassination before it happens.
In the altered scene filmed for the "BBC Six O'Clock" version, Haldane's hairstyle is completely different to his usual style, due to the hairdresser on the day not being able to match the original.
