Heightened awareness is always a good thing. Pepper spray or mace are illusions of self defense, and only in the illogical mind of an anti gun tyrant is the discussion about “illusions of power”.
Liberal solutions to avoiding becoming a victim of violent criminals always boils down to hiding in your room or traveling in a pack like hyenas hoping to be the last one eaten. It's not very comforting when you're in the crocodiles mouth and have no means of escape.
Utter moron.
Pulling a gun out and killing another human being is hard to do even if you are well trained and prepared to do so, at close range that hesitation will get you killed faster than anything.
A gun isn't a cure-all for common sense, and for many young women a can of mace or pepper spray would be a better choice if they are not hesitant of using that like they would be about killing someone.
