iraqi or gin bigin, but flefs h this country. there s no way for us to stop a person who wants to carry out a lone wolf act of violence. we don t know whether or not what happened in germany was a product of the islamic state directly, someone inspired by the islamic state, and the method that was used here is simple enough that it doesn t take a lot of skill, it doesn t take training, it doesn t take traveling to syria or iraq or afghanistan to learn how to do something like this but this is something that s been promoted by isis and al qaeda for years, this concept, and we re seeing it sporadically. that means there is no massive wave of people waiting in the wings to carry out these attacks. they will happen. but i think we can t live in fear of that and i don t think people should change their travel plans or what they re doing for the holidays based on this one incident. this is a very tragic and sad incident but it s not the end of civil order in the united states or germany.
