After watching the Laken Riley trial I ordered Birdies for me, my two daughters, and eight females on my work team. Many of us walk to/from parking garages at work, or to our cars after evenings out shopping or hanging with our friends, which can be scary. Simply taking a walk/jog alone is a risk for women. I believe the Birdie might make an attacker hesitate (or even run to avoid the attention), and that extra few seconds can save lives.
