I feel like he partially blamed by saying they can statistically reduce rapes - The problem is that for most rapists those techniques about body language don't work. Women who don't walk alone at night, who dress conservative clothes, who avoid talking to strangers and drink little alcohol are still abused, so in my opinion this idea is not a good one. Psychopathic rapists look for vulnerability like Tf00t said, but average rapists don't care much, they are opportunistic and seize the chance.
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
