I sometimes smirk sarcastically when the picture on the wanted poster is a previous mug shot. It seems the phenomenon is the same in Germany with international terrorists as it is in the U.S. with repeat offender criminal thugs.

BERLIN — The prime suspect sought in the deadly attack on a Berlin Christmas market — a 24-year old Tunisian migrant — was the subject of a terrorism probe in Germany earlier this year and was not deported even though his asylum bid was rejected, a senior official said Wednesday.

The suspect — who went by numerous aliases but was identified by German authorities as Anis Amri — became the subject of a national manhunt after investigators discovered a wallet with his identity documents in the truck used in Monday’s attack that left 12 dead, two law enforcement officials told The Washington Post.

Meanwhile, a clearer portrait took shape of the suspect, including accusations that he had contact with a prominent Islamic State recruiter in Germany.

German authorities issued a 100,000 euro ($105,000) reward for information leading to his capture, warning citizens not to approach the 5-foot-8, 165-pound Amri, whom they described as “violent and armed.”

His record, however, further deepened the political fallout from Monday’s bloodshed — pointing to flaws in the German deportation system and putting a harsh light on Chancellor Angela Merkel’s humanitarian bid to open the nation’s doors to nearly 1 million asylum seekers last year.

Really? You don’t say. So shocking.

If you never allow the trash in, then you don’t have to worry about getting rid of it.

Six known aliases. I wonder if he gets six welfare checks.
