Foriegn police forces all have one modus operandi ...
(1) Arrest the nearest innocent foreigner(s).
(2) Tell the Press you have successfully apprehended the criminal.
(3) Allow the actual criminal to get away, while you are wasting time interviewing the innocent foreigner(s).
(4) Spend the next few years trying to collect "facts" which seem to support your incompetence, while ignoring any real evidence.
(5) Take great exception when any other foreigner points out that you are, in fact, totally incompetent (or, more probably, simply corrupt).
