In Re Anthony Ketassda Lemicy

Does the guilty verdict that comes about at the end of a pro-se litigantsetrial, outweighs the Constitutional violation of having the defendant shackled during their entire proceeding without a hearing or showing justification ?

Is the burden still upon the government to prove that the pro-se litigant didn't suffer any prejudice due to being seen in shackles, or is the burden upon the defendant to present contrary evidence to challenge the conviction in order to have protection of a Constitutional right.?

Does the District Court, and the Appellate Courtihave the i discretion to disregard a Constitutional right that has deep roots in common law dating back to the 18th century ?
