The written ramblings of one of the men accused of plotting to kill the star were shown to a jury.
Kevin Liverpool, 35, wrote down in a diary his thoughts about the Devon- based soul singer.
One entry said: “God doesn’t give a fuck. Protect yourself from this. Remember Jocelyn Stone. God let her take the piss.”
Other diary entries talked of the need to buy a semi-automatic gun, a gun holder, a silencer, and infrared equipment, as well as a “ninja sword”.
They had planned to steal as little as £2,000 (€2,350) from the multi- millionaire.
Liverpool had also written a reminder to buy a hooded top, car insurance, a safe, and open a bank account, Exeter Crown Court heard.
He wrote of “war”, “warlord £1”, and of “missions” to “rob” and “discipline”.
Liverpool and Junior Bradshaw, 32, are charged with plotting to rob and kill Stone before dumping her body in a river in Jun 2011.
The defendants, both of St Stephen’s Close, Manchester, deny charges of conspiracy to murder, conspiracy to cause grievous bodily harm, and conspiracy to rob.
The diary was seized by police when they raided Liverpool’s flat in Longsight, Manchester, after he had been arrested in Devon.
Each page was covered in handwritten scrawl, in either blue or black ink, with much of it crossed or scribbled out.
Detective constable Katherine Joyner took the jury of 10 men and two women through the diary.
She said there were quite a few references to urban slang words, such as “wet” — meaning to repeatedly stab someone until their clothes are soaked with blood — and “popo” – short for police.
Liverpool had also written a list, numbered 1, 2, and 3, of “rob”, “wet/injure” and “death”.
Liverpool refers to Stone, who gave evidence to the court on Tuesday, as “princess”.
In the diary other music stars were listed, such as Dizzee Rascal, Eminem, Beyoncé, Chris Brown, and Girls Aloud.
Jurors heard that a stash of weapons was found in the defendants’ car.
A uniformed PC found a samurai sword with sheath, two knives, and a length of green garden- style hose- pipe in the boot of a Fiat Punto being driven by Bradshaw.
On the back seat of the car, police recovered a black hooded top and a black and grey rucksack.
The rucksack contained a roll of black bags, a roll of black tape, a hammer bought for £1 from a Manchester DIY store, a black and yellow spike, spark plugs, a sock, and a carrier bag. A second £1 hammer was found in the front passenger footwell, along with three black gloves and a black hat.
A black balaclava was also recovered as well as AA Route Planner printouts from Manchester to Devon, the court heard.
Other diary entries referred to “Jocelyn RIP — try to get info. Rob and kill.’
The trial continues.
