Happy slapping was a fad originating in the United Kingdom around 2005, in which one or more people attack a victim for the purpose of recording the assault (commonly with a camera phone or a smartphone). Though the term usually refers to relatively minor acts of violence such as hitting or slapping the victim, more serious crimes such as the murder of a retired care worker,^[1] and sexual assault were also occasionally classified as "happy slapping" by the BBC.^[2]

The general availability and affordability of mobile phones with integrated video cameras for the first time in the mid 2000s, in addition to their ease of use, meant that, compared to in previous decades, little if any planning was required to carry out and film such an attack. Similarly, the end product was more easily watched and circulated for entertainment than ever before, spreading through informal networks of person to person sharing. Contemporary media commentators suggested that the craze was inspired by such television shows as Jackass, Dirty Sanchez and Bumfights.^[3][4][5]

"Happy slapping" started in the south London Borough of Lewisham,^[6][7] in a format known as "Slap Happy TV", where a happy-slapping video would be recorded, and then watched by dozens of people like a TV show, but in the form of a montage. Videos of Happy Slapping were commonly circulated via Bluetooth on mobile phones. The first newspaper article to use the phrase "happy slapping" was "Bullies film fights by phone", published in The Times Educational Supplement on 21 January 2005, in which reporter Michael Shaw described teachers' accounts of the craze in London schools.

Gary Martin, writing on "The Phrase Finder" website described the phenomenon as: "Unprovoked attacks on individuals made in order to record the event, and especially the victim's shock and surprise, on video phones."^[8]

Martin wrote that happy slapping "began as a youth craze in the UK in late 2004. Children or passers by are slapped or otherwise mugged by one or more of a gang while others record the event on video and then distribute it by phone or Internet. Initially the attacks were, as the phrase would have us believe, fairly minor pranks ... As the craze spread the attacks became more vicious—often serious assaults known in legal circles as grievous bodily harm."^[8]

When the international media attention surrounding attacks abroad reached a high point, a girl was sentenced to eight months in prison.^[9] She was sentenced on a number of counts including previous crimes. ^{[clarification needed]}

A common punishment in 2007 was a fine or up to 40 days in prison, suspended if the attacker has no previous record.^[10][11] The attacker shall be liable to a fine or imprisonment for any term which does not exceed 3 years.^[12] Happy slapping is judged as "simple battery" as defined by section 244 of the Danish Criminal Code.^[12]

In February 2007, an amendment aimed at criminalising "happy slapping" was added to a law "on the prevention of delinquency" by the Parliament of France based on a proposal from then Interior Minister Nicolas Sarkozy.^[13][14] The anti-happy-slapping clause appears as the last part of Article 44, which also deals with ambushing law enforcement personnel. The law equates filming or photographing certain classes of violent crimes, including severe beatings and rape, with being an accomplice of such crimes. The law makes it illegal to broadcast the images of such crimes, punishable by up to 5 years in prison and/or a €75,000 fine.^{[citation needed]}

The law does not apply to those who took the above actions in order to obtain evidence in court, or as professional journalism. Professional journalism is delimited in France by the "press card", which is awarded by a commission representing journalist unions and press organisations.^[15] As defined by law,^[16] a professional journalist is one whose main activity is professional paid journalism.

The bill was signed into law on 5 March 2007, despite some organisations, including Reporters Without Borders,^[17] and the French chapter of Wikimedia,^[18] arguing that this clause created a legal discrimination in criminal law between professional journalists and ordinary citizens practising journalism. Specifically, it was argued that citizens filming incidents of police brutality and publishing such information online could be intimidated by law enforcement into remaining silent, or prosecuted for their actions. This criticism was relayed by the international media.^[19]

French President Nicolas Sarkozy declared to Reporters Without Borders that "the spirit of the law is not to infringe [on] freedom of information. However, if the least doubt subsist[s], then I'm in favour of a clarification of the law."^[20][21]

In March 2008, a teenage girl who filmed the fatal beating of a man on her mobile phone was sentenced to two years' detention in the first prosecution of its kind in the United Kingdom. The judge stated that the courts had to make an example of such youths. She had pleaded guilty at Leeds Crown Court in February 2008 to aiding and abetting the murder of Gavin Waterhouse, 29, from Keighley, West Yorkshire. Mark Masters, 19, from Keighley, and Sean Thompson, 17, from Bradford, were sentenced to seven and six years, respectively, after admitting to murder. Waterhouse died from a ruptured spleen after being beaten in September 2007.^[22][23][24]

Just before the attack, the girl was handed a mobile phone by one of the attackers and told to "video this", prosecutors said. She approached Waterhouse, asked for money, and recorded the subsequent attack. She was sentenced to serve a two-year detention training order. Police said they were satisfied with the court's decision. The Crown Prosecutor said "this is the first time a suspect in England and Wales has been successfully prosecuted for aiding and abetting murder or manslaughter, for the filming of an inaptly called 'happy slapping' incident".^[25]
