They are proving it, The Halton Police review was released yesterday...results? Unfounded as they initially reported...Of the year 2016 cases reviewed, Halton Police found 15 did not occur, the remaining 42 cases were found to not have been true after a "thorough investigation." fyi..not true is code for 'a lie'.
The math indicates just shy of 1 false accusation per week during 2016...just in Halton.. 
 Thankfully.....57 lives not ruined.
We eagerly await the result of the other Police forces. I suspect it won’t be long before we have actual proof that the 2-8% false accusation stat is complete crap. It's much, much higher.
I find it funny that those who are least likely to be the victim of a false accusation (women) are the first to proclaim loudly that they rarely happen.
Don't be angry at the Police, be very , very angry at the vast number of women who've lied about bring assaulted. Your beef is with them.
