CCTV, bodycam and smartphones - we have never been more filmed than we are today.
The technology we now take for granted has transformed criminal justice, investigations, prosecutions, and guilty verdicts in court cases.
From a machete attack, to an abduction to violent sieges and a hit and run, string of perpetrators has been brought to justice in recent months because they were caught on camera.
Here, the Manchester Evening News looks back at some shocking footage.
The horrendous broad daylight machete attack
Mujtaba Saeed-Ahmed launched a shocking machete attack, on a busy street in broad daylight.
The horrifying attack was caught on CCTV and showed him arrive on Bury Old Road in a taxi, armed with a fearsome two foot long machete.
Drug dealer Saeed-Ahmed, 22, had been confronted by his victim, who believed that Saeed-Ahmed had his girlfriend working for him.
The pair had argued over the phone before Saeed-Ahmed arrived, at about 7pm on August 2.

Further shocking footage showed the aftermath of the stabbing, as the victim tried to stop his girlfriend leaving in a taxi with Saeed-Ahmed.
The victim suffered a deep wound to his back, which caused a punctured lung and a fractured rib.
Jailing Saeed-Ahmed for seven years, the judge said: "It was a short-lived but brutal attack.
"That is a busy main artery into this city, at the time of the attack it was busy with moving traffic and pedestrians all going about their lawful business."
The ugly fracas in JD Sports
It was a busy Saturday afternoon in the store, the first time the branch of JD Sports had opened since Covid.
Children were forced to watch on in horror, cowering behind their parents, as a shocking brawl erupted.
A baton was brandished, and mannequins and shop furniture were used as weapons during the ugly fracas at the store on the Fort Retail Park in Cheetham Hill.
Cain Gordon, 20, Levi Murray, 19, were both jailed for their part in the incident.

In a statement read in court, the floor manager at JD Sports said: "This was the first Saturday opening since Covid.
"We were extremely busy and the store had lots of children in with their parents, many of these ran away from the fight, hiding behind their parents.
"At one point, a father is holding an approximate one year old daughter in his hands, as one of the victims brushes past him, attempting to move away from the attack.
"As much as I've seen fights in the past, this incident has left me shook up."
Gordon, of Crumpsall, was jailed for 22-and-a-half months after pleading guilty to criminal damage, possession of an offensive weapon in a public place and affray.
Murray, of Salford, was jailed for 20 months for the same offences.
The double amputee 'effectively abducted' by a stranger
To onlookers, it looks like a friend of family member is helping out a wheelchair bound patient.
But the reality was sinister.
The 67-year-old man had been 'effectively abducted' by a stranger, before being robbed.
The double amputee had been approached by Liam Dallimore at the Manchester Royal Infirmary, after he went to buy a bottle of coke from WH Smith.
He had woken up from a coma hours before, and learnt his second leg had been amputated.
After he started speaking to him, Dallimore, 29, started wheeling him away and took him to a secluded area in the hospital car park.
Dallimore then stole his bank card and keys, before pushing him down a hill.

He crashed into a wall, and the impact caused a wound to re-open in the stump of his leg which had been amputated years earlier.
Dallimore was jailed for three years and nine months, after admitting robbery and three counts of fraud.
"I think it is absolutely diabolical that someone can do this to a man with no legs," the victim said in a statement.
Mum mowed down by career criminal trying to get away from police
The mum had just nipped out to the shops to buy her kids some salad for tea.
But also out that Saturday evening was career criminal Ryan Deans, who was speeding around the streets in a stolen car.
Reaching speeds of 60mph in a 30mph zone on Cheetham Hill Road, he was being pursued by suspicious police officers.
When he made a right turn Deans left the road, mounting the pavement and hitting the 35-year-old in a horrendous collision.
She was thrown from her feet and was lucky to survive, suffering a broken back, leg and pelvis.
Police chased Deans' passenger Thomas Keogh after noticing that he had a knife, while Deans 'nonchalantly' walked away and went into a shop.
Deans, 33, from Eccles, was caught after his DNA was found on the driver's airbag.
He was jailed for four-and-a-half years after pleading guilty to causing serious injury by dangerous driving, handling stolen goods, driving while disqualified, failing to stop and driving without insurance.
Keogh, 29, from Fallowfield, was locked up for 21 months after admitting aggravated vehicle taking and having a blade in public.
Crazed knifeman Tasered in doctor's surgery
Moments after causing 'terror' and 'mayhem' in a doctor's surgery, police burst in and Tasered a crazed knifeman.
Two officers who were first on the scene in Stockport later received bravery awards.
Michael Brannigan had gone on a 20 minute spree across the town, robbing a pharmacy and attacking a stranger minutes before he entered Woodley Health Centre.
Brannigan, who suffers from mental health problems, had gone into the health centre earlier that day, behaving aggressively and demanding access to his medical records.

Later that day he returned and demanded to see the 'main man', wielding a knife in one hand and holding his walking stick in the other.
Receptionists fled to an office, holding a door shut as Brannigan tried to get in.
Acting with 'considerable bravery', the doctor took over holding the door to allow the receptionists to lock themselves in consultation rooms.
He tried to calm him down, but Brannigan used an office chair to smash a window.
He told the doctor that 'the others could leave', because it was the doctor 'who was the hostage'.
Brannigan was seen holding a meat cleaver, and tried to hit the surgery's practice manager with it.
Police arrived shortly after.
Brannigan was jailed for three years and five months after pleading guilty to robbery, two counts of affray, common assault, two counts of having an offensive weapon, and four counts of having an article with a blade or point.
The explosion which rocked a terraced house in Wythenshawe
It was a 'tremendous' explosion which ripped through a terraced house in Wythenshawe.
"He’s blew the house up, he’s blew the f****** house up," Clinton Parren's partner said after the shocking blast.
Parren, his partner and three children who were in the house all made miraculous escapes.
Parren, 43, and his partner, 32, at the time of the explosion, had been drinking when they had a row as he started to say she might leave him for a younger man.

Later that night Parren put a gas canister 'barely bigger than a can of coke', which he'd bought to cook soup with his children outside, on a cooker hob in the kitchen before turning the hob on.
The blast caused 'sheer panic,' blew out windows, lifted ceilings from their mounts and brought doors off their hinges.
Parren, who had been in a relationship with the woman for 10 years, had a 'persistent insecurity' because she was younger than him.
His family remain 'extremely supportive' but 'can't believe' what he did.
Parren, a joiner, was jailed for three-and-a-half years after admitting causing an explosion likely to endanger life or cause serious injury to property.
