Controversy
On 27 January 2020, Scott was arrested in Sydney's Moore Park after police were called to the area by security personnel. It was alleged that Scott had thrown a mobile phone at a passing motor vehicle and then had fallen asleep outside the Sydney Cricket Ground precinct. When police arrived at the scene, Scott allegedly pushed one officer away and punched the other officer in the face. He was the tasered and taken to the Sydney Police Centre in Surry Hills, where he was charged with six offences including two counts of assaulting an officer in the execution of duty, behaving in an offensive or indecent manner and remaining on trust lands after a request to leave. Scott was granted conditional bail and will appear in the Downing Centre court on February 20. The incident came only days after Scott had been interviewed by Fox Sports where he stated he signed for Canberra to "stay out of the Sydney rat-race and the Sydney fishbowl". Scott also told Fox Sports “I would have had too many distractions in Sydney and it just would have been a little bit too full on. It would have been easier for me to go out and end up … not in trouble, but just not take footy as serious as I did when I moved away and focused on it". On 31 January 2020, Scott entered not guilty pleas to all six charges at Downing Centre Local Court. Scott's lawyer spoke on his behalf saying “We will defend this to the last breath, The police clearly misunderstood their powers. There is a significant concern about the manner in which police conducted themselves. We’ll flesh it out in due course. We’re saying Mr Scott is not guilty of all charges". Scott's case is next due for mention at the Downing Centre on March 20. On 3 March 2020, Scott was cleared by the NRL to play in round one of the 2020 NRL season after they declared he would not be subject to the league's no-fault stand down policy. The NRL released a statement saying "Scott's charges carry a maximum five years imprisonment and do not qualify for an automatic no-fault stand down. Having considered the charges against Scott, the NRL has determined that he should not be prevented from playing whilst he responds to them," the statement said. "The NRL regards the charges as extremely serious and the Raiders have been advised Scott will face a significant penalty if found guilty of the charges".
