Background:
Next to the door of a new flat there was a roll of paper inside some plastic wrap. I didn't know what it was, so I took it down to inspect it.
Inside I found a roll of very stiff paper and Hebrew writing. A quick Google search and I learn that this is a Mezuzah. I don't know much about the Jewish faith, and I don't want to cause any more harm then I may have already.
This is a rented flat, I believe the landlord had the Mezuzah placed there in accordance to their faith.
Question:
In such a case would a non-Jew be "qualified" to simply put the Mezuzah back where it was, or should something else be done with it?
(I was linked to this question, which is very close to this one, the main difference being that I have removed the Mezuzah from its place, not know what it was until I looked it up on Google.)
