Maybe it's just me and how I see the world but.....

Let's take a look at what we KNOW about this situation.
1. We know this guy is a dirtbag.
2. We know he has your phone number.
3. We know he has your name.
4. We could be reasonably safe to assume he has or could easily get your address.
5. We know he spoke with an African accent.
6. We know nothing about him.

And now we want to start poking this dog with a stick...so to speak. I'm thinking perhaps discretion might be the better part of valour in this instance. I would think differently if there was any chance I could get my hands on him for sure...or the police, but as it stand the cards are all stacked in his favour imho.
Guess I'm just saying choose your battles wisely. That's my 2/100th's of a dollar.
Regards,
Dave.
