Throughout Europe, thousands of refugees are dropping off the face of the map. Hundreds have vanished from German refugee camps before they are even registered with the authorities, and the location of 4,000 people who lost their refugee standing in Denmark are at present unknown. Nevertheless, Sweden wins the Golden Hammer award for losing track of a mind-blowing number of refugees.
Sweden has to date taken in more refugees per capita than any other European nation, and they are quickly losing control of the problem. Their government had ordered over 21,000 of these individuals to go home after their asylum applications were turned down (doubtless, they are among the countless, single, working age men who have flooded into the continent). Having said that, 14,000 of them have basically disappeared, in lieu of submiting to deportation. Another 7,600 are purportedly accounted for, and awaiting deportation.
Sadly the police lack the manpower to impose the deportation orders, since many of them have been sent to carry out border security. That border security is also failing, since police officers are only permitted to make spot checks, and can not profile people by looks. Even when they do productively catch and deport someone trying to sneak in, their country of origin often forbids to let them go back home.
To paraphrase, nations like Sweden have surpassed the point of no return. The circumstances is so out of control that they have lost the power to maintain both internal and external security. At first they did not try to stop the mass exodus of migrants from the Middle East, but currently that they are trying kick some of these individuals out, they lack the capability to do so.
