"If a bomb is sent to someone and doesn't explode, my first thought isn't going to be "oh, they must have sent that bomb to themselves". That's what crazy people think."
When a group of people send fake bombs to other members of their group for political gain, it isn't crazy to think that something is off. And something is off. The 10,000 person caravan traveling through Mexico to the states, the dummy bombs sent to democrats...all right before the election. It isn't crazy at all to think that liars will lie to make themselves look victimized and blame the their opponents for their lies.
