Child soldiers
These children are impressionable and eager to please their minders. Just like any child soldier, they will not ask themselves too quickly if what they are doing is right.
They will be told that they are fighting terrorists, or organised crime. The parents will be so prowd of their child prodigy.
In reality, they may be doing damage to infrastructure and systems of peaceful political activists, environmentalists, the occupy movement, or `Anonymous´. They may expose data and identities of innocent people, who may subsequently be arrested, just dissapear of be killed by drone maybe.
African child soldiers wield machetes and machine guns, and are paid with food, drugs and sex. The UK child soldiers will be offered educational opportunities, and scholarships maybe.
The damage the UK child soldiers may inflict can be worse than that of their African counterparts. Of course they will never really know, because it is all state secrets.
Unless a whistleblower like Snowden comes forth in the UK.
