In X-Men: Days of the Future Past movie, the primary mission of Wolverine was stopping Mystique from killing Trask. With the help of Quicksilver, couldn't he achieve this within 0.0001 second? This looks easier than breaching the Pentagon.
They never even needed to identify Mystique. All Quicksilver needed was to be around Trask until someone shoots a bullet at him, divert the bullet and capture the shooter. Done!
Why exactly did Wolverine and company avoid using Quicksilver for this mission?
