The argument is not valid because it makes a fallacious inference from the premises. The fact that some dishonest people are found out does not necessarily mean that those people are politicians, so it cannot prove that some politicians are found out. Therefore, the argument is not logically valid. This can be shown with Venn diagrams by demonstrating that there is no necessary overlap between the sets of "politicians" and "people who are found out."
