Garda murder accused confronted officers wielding sword 14 years before fatal shooting incident

Garda murder accused Stephen Silver has shown a "pattern of self-dramatizing behaviour" to bring about confrontations and negotiations with gardai, a consultant psychiatrist has told the Central Criminal Court.

Professor Harry Kennedy told Mr Silver's trial that in previous encounters with gardai during his history of involuntary admissions to psychiatric units Mr Silver displayed behaviours that are not features of typical bipolar disorder.

He added: "They are angry and confrontational and dramatic. What happens in the course of mental illness is that ordinary personality features are exaggerated... that’s a product not of illness but of underlying personality."

Professor Kennedy disagrees with the assessment of Dr Brenda Wright who told the trial that Mr Silver's responsibility for the shooting was diminished due to a relapse of bipolar disorder.

Professor Kennedy said that a report on one previous encounter in September 2006 noted that gardai went to Mr Silver's apartment and he emerged from his bedroom with a long sword and dressed in a black helmet and leather gear. After a period Mr Silver put away the sword, lay down and allowed gardai to handcuff him and later had tea with them at the garda station.

Professor Kennedy said this was an example of seriously threatening behaviour with a "high probability of causing harm" which showed that Mr Silver was familiar with enacting personal dramas involving confrontation with gardai.

He asserted his control and "mastery of the situation" and then became compliant to bring an end to the confrontation, the professor said.

He pointed to other incidents which he said "illustrate a pattern of self-dramatising behaviour" in which Mr Silver would control a dramatic interaction with gardai. He said such behaviour is not a feature of bipolar disorder.

Mr Silver (46), a motorbike mechanic from Aughavard, Foxford, Co Mayo has pleaded not guilty to the murder of Det Garda Horkan knowing or being reckless as to whether he was a member of An Garda Siochana acting in accordance with his duty.

He pleaded guilty to manslaughter by reason of diminished responsibility, at Castlerea, Co. Roscommon on 17 June 2020.

Professor Kennedy told prosecution counsel Michael Delaney SC that in Mr Silver's account of the encounter with Gda Horkan, he described a series of "purposeful actions" such as taking control of the gun, pulling the trigger, standing back, supporting the gun with both hands, pointing and aiming and choosing to fire at the Mr Silver's trunk.

He did not throw the gun away but fired repeatedly. The professor said the capacity to form intent can be inferred from purposeful actions, where a person does "one thing after another after another".

Professor Kennedy said there was further evidence that when gardai arrived at the scene moments after the shooting, Mr Silver was able to make a decision to obey gardai by getting on the ground but also decided to what extent he would cooperate by refusing to be handcuffed around the back but allowing gardai to handcuff him to the front.

Professor Kennedy said this was a decision made for his own comfort and based on his past experience dealing with gardai. His interactions with gardai showed that he was able to act in his own interests, Professor Kennedy said.

In his garda interviews, Mr Silver showed "strength of will", resisted attempts by gardai to build rapport and showed himself to be "not at all suggestable".

At one point he feigned sleep for several minutes while gardai asked him questions, the professor said, showing an "intact ability to act reflectively and not impulsively and having regard to his own best interest as he sees it."

He said that "fleeting" ideas Mr Silver had the day prior to the shooting about a woman he was seeing being a member of MI6 were not fixed false beliefs and therefore not delusions.

He disagreed with Dr Wright's view that Mr Silver's decision to give away a motorbike to an old acquaintance earlier on the day of the shooting was evidence of his mental illness relapse.

Professor Kennedy said that the accused told gardai that he gave the bike away because he had too many and was thinking about getting rid of some of them.

The professor said this was a reasonable and rational explanation for why he did what he did. Professor Kennedy's evidence will continue on Friday.

Mr Delaney had earlier finished his cross-examination of Dr Wright in which he put to her various opinions advanced by Professor Kennedy. She said she disagreed with Professor Kennedy when he said that Mr Silver was engaging in "hostile repartee" when he became aggressive during interview and told gardai that he was a captain in the 62nd Cavalry.

She replied: "The suggestion of hostile repartee should be considered, but what is evident is the level of hostility and the types of behaviour in those interviews which is not adequately explained by hostility, it is in my view suggestive of mental illness."

Mr Delaney said that at one point in the interviews Inspector Brian Hanley began putting evidence to Mr Silver while Mr Silver was singing, speaking in Irish, making hostile jokes at the expense of the detectives and looking out the window. Mr Delaney said the professor's view was that this was not evidence of mania or psychosis but "a defensive effort to avoid the evidence being put to him".

Dr Wright said that Mr Silver's behaviour was "so bizarre and unusual that it is more in keeping with a mental illness". She said it would have been more appropriate for Mr Silver to reply, "no comment", if he did not want to engage.

She said that the level of hostility he showed was unusual and could not be "adequately explained simply by hostility towards gardai".

Mr Silver's records, she said, showed that when he became well following treatment after his 17 admissions to psychiatric units and after he had been treated at the Central Mental Hosptial in 2020, he was described as "easy to deal with". His records from Mountjoy prison did not show him to be erratic, aggressive or hostile.

There was an account of an attempted assault on Mr Silver by a fellow prisoner which the accused "managed in a calm and appropriate way," Dr Wright said. She said this was how she concluded that Mr Silver's behaviour with gardai was not his normal behaviour.

Mr Delaney said that Professor Kennedy noted that in his final interview with gardai Mr Silver's behaviour became more extreme, but said that "no psychiatric explanation was required for this other than Mr Silver's personality".

Dr Wright said Mr Silver's personality does not "adequately account for the types of behaviours he engaged in. I have no evidence based on the information I have reviewed that his personality was such that he was inclined to behave habitually in this manner."

She also disagreed with an assertion by Professor Kennedy that Mr Silver's previous encounters with gardai in which he "behaved badly" but was not prosecuted "gave rise to a learned impunity".

Mr Delaney said Mr Silver had an "expectation that he would not be dealt with through the criminal law" and being detained and questioned "led to increasing frustration that manifested as increasing rage and hostility towards gardai."

Dr Wright said that Mr Silver's previous episodes of aggression towards gardai were in the context of relapses of his illness and admission to psychiatric hospitals. She added: "Mr Silver's behaviour at the interviews is so out of keeping with the gravity of the situation and the context of the garda interviews that it is not sufficiently explained by the term, learned impunity. His behaviour is inappropriate to a degree that is more in keeping with a relapse of his illness."

The trial continues in front of Mr Justice Paul McDermott and a jury of seven men and five women.
