Finally, the letter writer refers to the "negligence and wastefulness" of Mayor Durant. The only action cited by the author is the approval of the bridge in the first place, which proves neither neglect nor wasting of anything. The sentence itself contains a non sequitur - firstly discussing the severe winters of the past several years, and then accusing Mr. Durant of waste and neglect. This accusation is unwarranted as well as unsupported in the author’s argument.
In summary, the author simply makes groundless accusations without providing any real support for his or her argument. To make the argument convincing, the author would have to provide evidence that Mayor Durant approved a faulty bridge design or an unqualified construction company that caused the bridge’s damage and traffic problems. The author should have also provided supporting details that show that the damage to the bridge is out of the ordinary and directly caused by Mayor Durant’s decision to use inadequate construction materials or a poor design. Without more support, the author’s point of view is unconvincing and not well reasoned.
