When I'm out in public I usually have a little Asp collapsible baton with me as well. I figure its good to have a less lethal option available since an assailant may not have a weapon but still be intent on hurting you. A few years ago while standing in line at the pharmacy a guy started staring at me like he wanted to start something. Never saw him before, I assume he thought I was somebody else. I never made eye contact with him and he moved on after his skank girlfriend got her meds. He was about half my age and pretty big. I had my pistol but we all know you're probably getting flushed down the judicial toilet if you use lethal force on someone who is unarmed, even if they are trying to hurt you.
