While not wishing to detract from the key issue that staff should be free from violence at work, it appears that an equally serious issue is being glossed over by some - that of allowing false information to be officially circulated (news, page 2, 28 October).

The end does not justify the means. The principle of feeding false information is a real problem for policy makers and those at the sharp end of the service. False data leads to false analysis and perpetuates ineffective problem solving, often through inappropriate use of resources. The tactical use of misinformation is at odds with open government.
