Had it been explosives in that baby stroller and a tragic event were to ensue, I'll bet hundreds of people would call to "witness" they had seen it. Pretty sad people are so self-absorbed and unconcerned about anyone except themselves.
That law enforcement and security ignored the stroller altogether is foreboding of the lack of seriousness with which they tend to possible terrorist threats. That reporter should have been taking down names and numbers and turning them in to Homeland Security. All it will take is one weak link and hundreds if not thousands will perish for that/those person(s) disregard.
I can imagine that the article about the baby stroller has generated a few phone calls to Homeland Security, from those who ride those subways......I hope so.
