No.
Even the vilest offenders are entitled to confidential and professional legal representation. That’s the American way. Attorneys are bound by ethics and law to defend their clients and work for them in good faith.
A legal firm representing a guilty client isn’t obstructing justice. It’s just performing a difficult job as provided by our laws.
No, I beg to disagree. A lawyer can defend one who has committed a crime, but a lawyer becomes an accomplice when he/she participates in or facilitates the criminality with the principal in a continuing criminal enterprise.
