A suicidal man made terrifying threats to go on a mass murder spree in telephone calls to the police, a court heard.
Mark Brown told an operator he would cause even more bloodshed than notorious killers Derek Bird and Raoul Moat.
A judge at Maidstone Crown Court rejected a recommendation that the 36-year-old be sentenced to supervision with a curfew.
"Heaven forbid that anything else should happen in the future," said Judge Philip Statman.
"No doubt, people will be asking: 'What did the judge at Maidstone do before passing the sentence he did?’ I need to know what is going on with this man.
"One has only got to look at the men he has mentioned in terms of what he said to police. You know what the circumstances could be."
Jo Cope, prosecuting, said Brown was in the Kings Hill area when he called 999 on August 7 last year and made threats, saying he had weapons.
"He said he was going to punish a lot of people and officers would require body bags," she said. "He went on to say Derek Bird and Raoul Moat were nothing on him."
He continued: "I am always the one pushed. Please understand this: This will be another Raoul Moat incident. I have dreamt of this for many years.

"Please don’t let me do something stupid. I am going to kill the first f----- that comes near me. This is going down in a blaze of bullets."
Mrs Cope said Brown made nine calls and repeated the threats. He spoke of being rejected throughout his life, how his wife had left him and he had lost his children.
"He said he was trying to ask for help and nobody was listening," said the prosecutor. "He was crying when he made the eighth call."
Brown was still in his car in Kings Hill when police arrived. He drove off and officers believed he was trying to provoke them into killing him.
He made emergency stops and at one point reversed into a police car at speed. A stinger device was used to puncture his tyres.
Brown, of Shoeburyness, Essex, admitted making threats and criminal damage.
Judge Statman adjourned sentence until February 2 to obtain more psychiatric information. Brown was granted conditional bail.
