VioGen is an algorithm used by the police – it’s a risk assessment tool. Based on a woman’s answers to a series of questions, it calculates the likelihood she will be attacked again so police resources can be allocated to protect those most in danger. The level of risk could be negligible, low, medium, high or extreme. Lina was recorded as being at ‘medium’ risk of a further attack by the man who was her ex-partner. Three weeks later, she was dead. VioGen’s critics are concerned about the number of women registered on the system who are then murdered by men who are former or current partners. Its champions claim that without VioGen there would be far more violence against women.
