@Jason Gott this is interesting topic and to be honest it’s creeping into a lot of different fields.
So let me start with I am a police officer in California and have been wearing a body camera for several years now. It’s funny to see everyone’s reaction, because it’s the same reaction we had when they were first introduced to us. “I don’t want one of those things recording me all day”. Now several years later most officers love the body camera because it gets us out of trouble more than it gets us in trouble.
If I owned a business and had employees, they would wear them. My friend owns a plumbing business and his employees wear them because he was tired of people complaining that his employees were creating damage. Now he can prove or disprove these claims.
As far as video recording, you can legally record anyone in a public place. So if you went to Starbucks and wore a body camera it would be fine. You only run into trouble if the other person has “an expectation of privacy”. Ie inside someone’s house.
I would think this is easy to overcome as you just tell people what you are doing and you explain its to protect them and yourself.
