When faced with a frenzied crowd of 2,000 people, there is probably little one could do.
The only saving grace would be to eliminate the possibility of getting into that situation in the first place.
Some things in life fall upon us because we either do not recognize or do not care to pay any attention to the approaching storm.
This guy should have noticed the 'pending storm'. It's not like any of us haven't been aware of the crazy shoppers and stampedes in the past...Circuit City, K-Mart, WalMart, etc.
Stay armed...stay away from crowds of frenzied shoppers...stay safe!
