Absurd? – Mugging pays off handily

The population of Great Belém left only in its misery by the government and a lack of action, interest and honesty by the police in the street, does not have another choice than ask the assailants to cooperate. After innumerous hold ups the owner of this small neighbourhood shop nailed the following text to the wall outside his shop:

It reads:

MISTER CRIMINAL
I beg you, after you have robbed me once again, to offer the stolen goods solely to me.
Buying the goods anew in the legal market is expensive and I know you are selling cheap.
I promise absolute secrecy as I don’t want to be arrested for fencing.
I ask your sympathy. You can check in here.
P.S. Please don’t steal this poster
