Scammer Anthony Tijan provides this photo of "diamonds" in a suitcase. It must be real. Of course, the same effect can be obtained by taking several large glass jars, smashing them into small pieces with a hammer or other blunt object, and then putting them into a suitcase.
WARNING: Do not try this at home.
Nothing like scammer ingenuity. Maybe they crashed their own cars just so they could have something to put in the briefcase. We could only hope.Those "diamonds?... No, man that's General Motors side window "popcorn" safety glass! Probably swept up at an intersection immediately after a side impact. Look very closely at the light green tint: dead giveaway.
