Just for your information:
The bomb attack on the german soccer team (where there they found letters with islamists taking the responsibility for it) was committed by someone short-selling stock options for that soccer club. The guy has just been arrested....
The shooting in Paris is probably not different. Instead of dragging down the stock options of a club, the extremists just want to boost the election chances of their fellow extremist.
@Masek Someone short-selling stock options sooner or later reverting to this kind of "technique" seems so predictable, it's quite depressing.
@frari Little surprise, but depressing nonetheless
