How is it Wal-Mart's fault, really?!

I know most everyone has heard about the man and woman being trampled at the Wal-Mart on Black Friday. Now, I'm sure there is plenty of blame to go around, but people seem to want to blame Wal-Mart. There were thousands of Wal-Marts, Targets, Best Buys, Circuit Citys, etc. all around the country that took the exact same precautions and did the exact same things as this Wal-Mart did and no tramplings occurred. I suppose one could argue that there must have been something specific about this store that caused the incident. I would argue that, in fact, but it would have nothing to do with the store. This incident has EVERYTHING to do with the people in line. They are the ones who couldn't wait, couldn't stop, couldn't help themselves to the point of trampling over people just to get a tv. That's who's to blame. Sure, that particular Wal-Mart probably could have taken extra precautions, if they'd known it was going to happen, but since it hadn't happened in previous years and since it didn't happen at any other store across America (who all took the same precautions), why should they have expected it. They shouldn't. That's the answer you don't want to hear, but there you have it. The people in line were shamefully ignorant and selfish. That's why this happened, pure and simple.
