Can a pro se plaintiff who brings a civil rights action amend his complaint after the court has entered judgment dismissing the original complaint?

A pro se plaintiff who brings a civil rights action should be "fairly freely" afforded an opportunity to amend his complaint, even if he makes the request after the court has entered judgment dismissing his original complaint. Bradley v. Coughlin, 671 F.2d 686, 690 (2d Cir.1982). In essence, a pro se litigant should be afforded every reasonable opportunity to demonstrate that he has a valid claim. Under the circumstances here, we think it was unreasonable and an abuse of discretion for the district court to refuse to accept the proposed amendment.
