UNITED NATIONS A UN human rights expert has criticised the US for failing to properly protect women from domestic violence, citing a 1999 Colorado child slaying case. 'The US Government should reassess existing mechanisms for protecting victims and punishing offenders, and establish meaningful standards for enforcement of protection orders and impose consequences for a failure to enforce them, said the UN Special Rapporteur on violence against women, its causes and consequences, Rashida Manjoo, a South African national. She said US laws on domestic violence lack substance and arent properly enforced. Manjoo singled out the case of Colorado woman Jessica Lenahan whose three daughters were killed by her estranged husband. The Inter-American Commission on Human Rights last week sided with Lenahan in a complaint against the US. The Washington-based civil-rights tribunal recommended the US government carry out a full investigation of the case and strengthen legislation against domestic violence. Not knowing where her daughters were, Ms. Lenahan contacted Castle Rock Police Department eight times on the evening of June 22 and the morning of June 23 1999. That morning, Simon Gonzales drove his pick-up truck to the department and fired through the window. In an exchange of gunfire he was killed. The bodies of the three girls were found in his truck. Manjoo noted that she conducted a fact-finding mission to the US earlier this year. 'In my discussions with Government officials, victims, survivors, and advocates, including Jessica Lenahan, I found a lack of substantive protective legislation for domestic violence victims in the US, as well as inadequate implementation of certain laws, policies and programmes, she added.
