I would agree with most everything others have said, but with a couple of exceptions. My only concern about the walking stick approach is this: As someone who often finds himself in need of the use of a cane for walking, I have the fear of a cane or walking stick sending a "victim here" message to potential evildoers. This is the same reason that I use the mirror-hung handicapped parking placard in my truck instead of getting one of the disabled license plates. The only time the placard is visible is when I park in what my doctor calls "Rock Star Parking".
I realize that the above statement is a LITTLE off topic, but my point is that a cane or walking stick can be seen as a sign of vulnerability by potential attackers and may serve to escalate the situation rather than de-escalate.
Remember, the only fight you ever REALLY win is the one in which you don't participate. DEESCALATE, DEESCALATE, DEESCALATE!!!
