The Langlands-Kottwitz method allows us to understand the zeta function of the Shimura variety, which in turn allows us to understand the Galois representations appearing in the etale cohomology of the Shimura variety, but only up to semisimplification. I will talk about a result that shows that a certain part of the etale cohomology of various abelian-type Shimura varieties is semisimple.
