A Longreach senior constable has avoided a conviction but was fined over an incident captured on video in which he pulled a gun on a Mount Isa couple for allegedly speeding on the Landsborough Highway.
Senior Constable Stephen Flanagan was found guilty of assault and deprivation of liberty in a Brisbane court in December last year over an incident on the highway near Longreach in May 2015.
Magistrate Paul Kluck ordered no conviction was recorded as the 46-year-old Flanagan suffered from post-traumatic stress disorder which was undiagnosed at the time of the incident.
This month Flanagan was fined $1500 for the incident.
Mount Isa couple Lee Povey and his partner Anna Lisa Cruse were on the highway when intercepted by Flanagan.
The dash-cam video showed Flanagan swearing and blowing his horn before pulling his gun on the couple.
Flanagan was captured screaming "f***ing pull over now, c***" and drew his gun on Mr Povey as he threatened to "put a f***ing hole in you".
Flanagan assaulted Mr Povey when he held the gun to his back.
On Friday, the court heard it was not uncommon for people with post-traumatic stress disorder to be unaware they have the condition or the extremity of their reactions.
The prosecutor said Flanagan's behaviour had a "significant" impact on Mr Povey, who feared no one would take his complaint about the incident seriously.
