I still carry my voice recorder though I don't always turn it on unless I'm in public. But I look at it as another self defense tool that is there just in case. Just as my firearm is there for just in case, the recorder also is to protect me if a confrontation ever does happen it is kind of a behind the scenes witness in such an instance. If I don't need the recorder then why do I need a firearm? Because I'm not a fortune teller and can't judge the future from the past aka just because I haven't had to deploy my weapon in the past doesn't mean I never will need to in the future, and the same goes for the recorder.
Complacency is bad thing, if we forget the past or past experience then we are bound to repeat it. Let us not live in the past but learn from it and remember it. Let us not be complacent but always remember our accomplishments and the price for those accomplishments and lets us always be at the ready to defend them.
