C.    a text message is just another trigger.  nothing more, nothing less

There has been much talk about guns these days.  Sometimes guns malfunction.

Think of a cell phone as a weapon.  A gun.  Think of a text message as a bullet.  Now picture tens of thousands of phones and tens of thousands of messages.  (Roger Waters - Rapid machine gun fire).

I've already touched on the variety of triggers that induce panic.  I do think it's critical to understand that this is a universal, human concept.  Although most major stampedes occur at religious festivals and sporting events with a concentration in Europe, Africa, and Asia, stampedes are fundamentally a human problem.  When it comes to stadiums seating, some people will wrongfully try to convince you that the problem revolves around general admission vs. an assigned seating approach.  This has no legitimate bearing on the ability to induce panic.  I suspect, since stampedes in the U.S. are less frequent, there also might be a general "Americans aren't as susceptible to panic like other cultures" consensus.  I strongly believe this to be erroneous.

If anything, we are a paranoid, yet strangely complacent culture with a high degree and obsession with technological interconnectivity- this would lead me to believe that we're very susceptible to an AGS.
