Yes it will. There is not any DA, or even assistant to the assistant DA that is dumb enough to prosecute you for using a cane in self defense. In fact, when I was 34 years of age, and I had a rough knobby blackthorn stick with me, a local sheriffs deputy made the mistake of hastling me over my stick. This was long before the ADA. In the end, he was suspended, and the department settled out of court for the 'undisclosed sum'. These days, cops ain't even gonna touch that issue. Espcially if there is a disparity of force issue. The local senior center gives lessons in how to use your cane for defense, and one of the people teaching it is my own son, a Montgomery Country police officer.
