We study the Leray spectral sequence for the integral \(\ell\)-adic cohomology of torsors for abelian schemes. For an abelian scheme over a smooth, geometrically irrducible curve over a finite field, we relate the question of whether a torsor is determined by its étale cohomology with the conjectured finiteness of the set of all such torsors.
