The moment Michael Sandford emerged from the crowd at the rally and tried to grab an officer's gun has been captured on a police body camera.
Michael is seen walking up to an officer before he asks about getting an autograph from Donald Trump - who at the time was still on the campaign trail.
But when the officer leaned forward to tell Michael he would have to wait until the Presidential hopeful finished speaking, the 20-year-old from Dorking tried to grab his gun, but it got caught in the holster.
Within seconds another two policemen were on the scene and Michael Sandford was wrestled to the ground and handcuffed.
The picture of him being frogmarched out of the building would be beamed across the world.
His mother Lynne says she is thankful he wasn't killed:
In the car park, Michael, who's from Dorking in Surrey told the officers he wanted to assassinate Donald Trump, who he argued was a racist and needed to be stopped.
In the video footage, he is heard saying: "No one should be racist."
The officer tells him everyone is entitled to have an opinion and say what they want to say.
But Michael disagreed: "Well you know what? They need to change the constitution."
Michael was adamant.
He replied: "How do you think racism is correct."
The 20-year-old from Dorking in Surrey would later admit illegal possession of a firearm and disrupting government business.
He could have faced 20 years behind bars, but under a plea bargain deal he was sentenced to a year and a day.
A week ago his family were at Heathrow airport to welcome him home.
After hugging his mother Lynne, grandmother, Christine, father Paul and little sister Jessica, Michael said he was happy to be home but was feeling overwhelmed.
It is now known that Michael was having a psychotic episode on the day of the incident.
He was just 20 feet away from the future president when he was stopped .
Michael, who has autism and other mental health conditions, has told his family he was hearing voices.
He feels he was also being influenced by his girlfriend's political views.
Michael served most of his sentence at the Southern Nevada state detention centre.
He was on suicide watch and had several spells in solitary confinement. Now he is back home, the focus is restoring his mental health
Mum Lynne said: "It's going to be a long, long journey and it will quite often be two steps forward, one step back. He's been through a terrible, terrible ordeal and that's going to take him a long time to recover from properly. So, it's baby steps but we're there to support him."
