A European man dressed in full ISIS fighter regalia decided to videotape himself crossing from Denmark into Germany. The resulting video demonstrates just how easy it is for terrorists to travel between Europe's incredibly porous borders.

The video is especially poignant considering Berlin, Germany was recently the site of an Islamic terror attack that killed 12 and wounded dozens more. The manhunt for Anis Amri, the man responsible for the deadly attack, ended in Italy after had passed through Germany's unguarded border.
