An NFL team owner accuses Putin of stealing a ring of his, which he handed him over during a visit to have a look at it. 
Could a president of a country steal a ring?
Why not? He kills people for fun, would a ring be a problem?’
On the other hand could a business man tell lies?
Why not? He tells lies every day, would he stop now?
You have too much controversial evidence to find the solution. Typical of any philosophical problem. This is why only Philosophy can solve this: The ring does not exist! Everything is in our mind! 🙂
