Sky People/Crime and Punishment

Among the various human factions on the ground and in space, punishments for various crimes take many forms depending on the severity of the crime and the age of the criminal.

Juvenile Lockup


If someone under the age of 18 is arrested, they are held in Juvenile Lockup until they turn 18 at which point they are tried before The Council for the crime(s) they committed. From this trial, the accused can either be acquitted or found guilty and floated. After the oxygen shortage on the Ark reached critical levels, these underage Delinquents were sent to Earth to see if it was survivable and to give the Ark more time to fix the life support problem.

Flotation


Capital Punishment in the form of Flotation occurred on The Ark when someone the age of 18 or older broke the law. This is a type of execution where a person is put into an airlock chamber which is then opened, exposing them to the outside elements and forcing the person's body to be sucked into the open space, resulting in death from lack of oxygen and negative pressure. Rarely, an adult prisoner may be granted a stay of execution by The Council, as in the case of Abigail Griffin.

Death by a Thousand Cuts


Capital punishment in the form of Death by a Thousand Cuts occurs when every single member of the clan takes a turn cutting the convicted before feeding them to the bugs. For more egregious crimes (as in the case of Finn Collins), they start with fire and take the hands, tongue, and eyes. Everyone gets a turn with the knife before the Commander ends it with the sword, if the person is still alive by then.

Harvest Chamber
Since Mountain Men were not able to adapt to the outside as they had remained in Mount Weather the entire time, they eventually realized they could use Outsiders to filter their blood of the radiation that was poisoning the Mountain Men. Through the Harvest Project, Mount Weather detained hundreds of Grounder prisoners at a time over a 56-year period. They built a Harvest Chamber filled with cages to hold the Grounders pending Harvest. Each Grounder was used multiple times before the Mountain Men disposed of them, sometimes still barely alive, by leaving them in the mines for the Reapers to feast on.



Quarantine
Within Mount Weather on Level 3, there were quarantine rooms used to house the 48 Delinquents after they were brought to Mount Weather in the first season finale. It was later used to imprison the overthrown president of Mount Weather, Dante Wallace.

Level 5
When the Mountain Men began harvesting the Delinquents of their bone marrow, an additional room was set up with 47 cages specifically to house the Delinquents. Only two Delinquents, Monty Green and Harper, were ever imprisoned there before their release by President Dante Wallace. After Cage Wallace took over the presidency, the Delinquents resisted arrest and imprisonment causing most of Mount Weather to be irradiated. Eventually, the Delinquents' dormitory on Level 5 was turned into a make-shift prison and the Delinquents and other captured Sky People were chained to the walls to await bone marrow harvesting.

Sky People Stockade
Shortly after Camp Jaha was established, a secure room was quickly set up to detain prisoners (specifically Bellamy and Murphy). Over time, this room became known as the "Stockade" as more people were imprisoned.

Grounder Prison
The Grounders also have their own holding cell for prisoners. After Thelonious Jaha was sold to a bounty hunter, he was delivered to the Commander and imprisoned in an underground subway station. When Marcus Kane followed Rivo to a Grounder village, he was also apprehended and placed into the same room with Jaha. The Commander expected the two to battle to the death in retribution for the Tondc massacre, however, ultimately ended up releasing both of them in an attempt to get the Sky People to leave their lands.

Banishment
Once on earth, the Delinquents quickly discovered they needed rules to survive. As co-leaders of the 100, Clarke Griffin and Bellamy Blake ordered the banishment of John Murphy after the suicide of Charlotte.

In the Grounder culture, there are Grounders who have no clan because they or a family member may have been seen as a "stain on the bloodline" due to birth defects and cast out. The Woods Clan also banished Delano and his men. Delano was a thief but it is unknown what the others did.

Shock Lashing
After the rest of the Sky People arrived on earth, they put into effect the Exodus Charter. Under the Exodus Charter, unauthorized use of firearms was to be punishable as a felony with 10 shock lashes. Abigail Griffin was punished after committing said felony (providing guns to the Delinquents).

Trivia

 * In the book, before Flotation, a nurse injected the convicted person with a lethal serum and then the corpse was sent into space.
 * Bellamy Blake was charged in absentia for his attempted assassination of Chancellor Jaha in Pilot in order to get on the drop ship with his sister, Octavia. He was later pardoned in Unity Day by Chancellor Jaha after revealing it was Commander Shumway who had set it up.
