Terrorism concerns can lead to automatic disqualification from asylum. Even before the events of 9/11, people with terrorist connections were ineligible for asylum and subject to deportation. However, laws passed by Congress after 9/11 in 2001 and again 2005 have broadened restrictions even further. Under current U.S. law, any person who provides "material support" to terrorists will be refused asylum. Since there is no exemption for cases of coercion, even acts such as providing drinking water at gunpoint to terrorists are to be considered material support.

^This.

The Convention relating to the Status of Refugees allows to deport convicted criminals and that is what Germany is planning to do now (though I doubt I'll ever see it actually happen...).
