For those living in countries, too dumb not to allow their weakest citizens, to defend themselves against rapists and thieves, with at least a minimum non-violent deterrent force. Just get yourself small safe bottles, that can spray narrowly, to a good distance, and filter out properly the mixture, not to clog the spray. If needed, don't be afraid to spray generously, directly in the eyes of aggressors.
Every women should carry at least one with them outside for their protection, ready for a few direct sprays in the face and the eyes of aggressors, before getting out the bigger artillery. (French Canadian video)
