I am not sure to be honest.
And you should not. It is very sad that the country has come to this. I was taught a man's word was his bond. A handshake was as good as a man's bond. That all changed over 40 years ago when someone went into court and lied against my father.I trust almost nothing these days. I understand quite well.
If you don't believe in the bible, it doesn't take a whole lot for someone to lie after placing their hand upon it.
