I vote we change it too "believe woman after an unbiased investigative process supports their claims"
No such investigative process or criminal legal process exists, so do you have a proposal up your sleeve to replace the current systems in order to create this?
There is plenty of evidence demonstrating that the investigative process deployed in response to reports of rape is a long way from unbiased (it is biased against victims), so presumably that process cannot be what you are referring to here.
It's also not "some convictions" being missed, it's 0.5% of rapists being convicted and 99.5% of rapists being left free and unencumbered by consequences of any kind.
While 100% of victims are left more traumatised and more damaged by a system that starts from the position of blaming them and continues that way throughout the entire legal process. Again, evidence supports this as the outcome of the US and UK approach to dealing with rape reports.
No reasonable person would support such a failing system.
Our rape laws and rape processes were created by the people who rape in order to serve their needs. They not only fail rape victims but cause damage to them as a matter of course (not an occasional exception, but routinely by design). If that weren't the case "believe women" stances would not be necessary.
Your ignorance is spectacular.
