Bendis is taken away by police in Marvel's Defenders

Brian Michael Bendis had a long and successful history with Marvel Comics--writing Daredevil, Ultimate Spider-Man, Avengers, New Avengers, Uncanny X-Men, Alias, The Invincible Iron Man, and Guardians of the Galaxy among others. His final book for Marvel was the Defenders, a team that united Luke Cage, Jessica Jones, Iron Fist, and Daredevil (like the Netflix series).
