Perplexing Words

I had so many questions after seeing this sign:

1. Why was this guy asleep in his car?
2. Why was this guy so deeply asleep in his car that he couldn't hear/feel someone taking something from the vehicle?
3. Out of the important things he mentions he wants back (journal, magic stones, sacred items), which is the one worth $100?
4. What is the LAW OF THREE?  (I've since figured it out.  I think.)
5. Is that the proper use of "whomever"?  (No.)
