Referees watching slow motion videos flash more red cards

Russian police stretched to the limit

  • MOSCOW: Police staffing is so stretched in several Russian cities as officers are deployed to bolster security at soccer World Cup venues that one union leader says criminals could benefit. Several police officers in cities across Russia said their staff were working long hours, patrols had been reduced and response times to incidents had slowed. Russia has deployed thousands of police to the 11 cities hosting matches to deal with an influx of potentially rowdy fans and other security threats such as the risk of Islamist terror attacks. A senior regional police officer told Reuters that officers were on call 24-hours a day and, even when not working, needed permission to leave their accommodation. He said the working day typically lasted around 14 hours. — Reuters

London, June 11

Football referees penalise players more severely when watching the action in slow motion compared to real time, according to a study. The study comes at a time when the debate on video assistant refereeing (VAR), which will be used in the World Cup, is raging on.

Researchers from the University of Leuven in Belgium studied the response of 88 elite football referees to video clips of a foul warranting a yellow card. They found no significant difference in the accuracy of a referee's decision about whether a foul had occurred or not, with slow-motion videos (63 percent accurate) compared to the real-time videos (61 percent accurate). However, the judgement of intention or force behind a foul differed. More red cards were given by referees watching in slow motion compared to those watching real time video playbacks. The study concluded that although slow motion playback could be a useful tool in assessing some decisions, such as off-side and determining the exact impact of a contact, it may not be the best tool for decisions that involve judging human behaviour and intention. — PTI
