I know that it's advisable to keep a digital voice recorder on you all the time in order to document any encounters with uninformed Law Enforcement Officers.
So does anyone just turn the thing on at the beginning of the day and let it run? Some of them have a LOT of recording time. It seems to make sense to just delete the large file each day and start over unless you had an issue, in which case you'd download it.
I'm just thinking that getting the thing started up might be something easily forgotten. I also don't like the idea of sticking my hand in my pocket if you have a nervous police officer on the loose.
