On June 18, 2016, at a rally for Donald Trump's 2016 United States presidential campaign in Paradise, Nevada, Michael Steven Sandford, a 20-year-old British citizen, attempted to grab the service pistol of a Las Vegas Metropolitan Police officer providing security for the event.

[3] Sandford was charged with disorderly conduct and with being an "illegal alien in possession of a firearm" for having previously rented a pistol at a shooting range.

[6] While the incident did not receive sustained media coverage in the United States,[7] it was the subject of a documentary commissioned by the BBC in February 2017.

[1][13] On the evening of June 17, Sandford joined a queue at the Treasure Island Hotel and Casino for the following day's rally.

[1][14] The event was under the protection of the United States Secret Service, and magnetometers were used to detect any weapons brought into the venue.

[20][21] After being taken into custody by the Las Vegas Metropolitan Police Department, Sandford was handed over to the United States Secret Service.

[22] After agreeing to waive his Miranda rights, Sandford was interrogated by two special agents, during which time he stated that his intent had been "to kill Trump", that "if he were on the street tomorrow, he would try this again", and that he had been planning the attempt "for about a year".

[20] Due to his mental health conditions, Sandford was kept in solitary confinement and repeatedly put under suicide watch.

[24][26] Sandford appeared in a Nevada District Court on June 20, 2016, where he was charged with committing an act of violence on restricted ground.

[19] On September 13, 2016, Sandford pleaded guilty in the United States District Court for the District of Nevada to charges of being an illegal alien in possession of a firearm (this pertaining to the firearm he had on June 16, 2016, rented for practice at a shooting range) and impeding and disrupting the orderly conduct of government business and official functions, saying "I tried to take a gun from a policeman to shoot someone with, and I'm pleading guilty.

[43] The sentencing judge, James C. Mahan, acknowledged Sandford's mental health issues, stating, "I don't think you harbored malice in your heart ... You have a medical problem ...

The Order was successfully opposed by Sandford's attorney, who evidenced that the legal test could not be met, resulting in the claim being dismissed.

[57] They also suggested that Trump and his supporters declined to make political capital from the incident,[7][57] as "a white British non-Muslim man did not fit his narrative of 'threat'".

The film was critical of mental health care in the UK, stating that "NHS resources [are] increasingly stretched by government cuts" and "There's also this difficult crossover period around 18 years old when someone passes from youth to adult services and people can get lost in the system.
