You are 30, I am 60, so you get 2x the times engagement I do. I am not shocked, but I am extremely sad to hear this has gone on in London. I am heartened to hear the man was finally stopped.
Here in the US, this initiative has begun, because men like this man will never be stopped until those who enable them are also caught and punished. This includes his supervisors at the Police and maybe even coworkers who saw it and did nothing.
If you are willing, please read and share. It should happen all over the world. https://medium.com/@asterling/holding-sexual-assault-enablers-responsible-52e149bce9b6
