Before I read this (.pdf permalink to non-jihadi web page), I didn't realize Casio watches and Arabic perfume were such robust indicators of jihadi terrorist affiliation....
“Exposing features of a Mujahid (both potential and active) include …. Outer appearance, for example, growing beard, even stubble, if only it is not a norm or a trend in the society. Also, use of [verbal] expressions, clothes and accessories (Casio watch, Arabian perfume, miswak) that are associated in public opinion with “militants” or “Wahhabists”.”
And an interesting factoid, if true:
“According to statistics of Russian security services, during the last several years, around 80-90% successful operations against Mujahideen have been carried out due to surveillance and tapping of mobile phones.”
