Questions need to be raised. Hydralic barriers were apparently taken out for replacement but there was little to replace them until the Super Bowl. Driver apparently found a weak point and took advantage of it. A lesson learned for next time at the expense of 15 lives is not acceptable. Miss Chief needs to be asked why nothing more substantial was installed as a temporay replacement or did it just slip her mind? No crime in raising questions. Make no mistake about it that the terrorist is 100% responsible for the lost 15 lives and the carnage he created.
