Final answer:
Legal professionals are bound by certain standards of performance and duty to inform clients of consequences such as deportation. Collusion and the exploitation of regulatory gray areas in business are illegal. The illegal substance trade constitutes a major part of criminal activity with wide-ranging effects.
Step-by-step explanation:
When dealing with clients involved in illegal acts, it is important for professionals, particularly in the legal field, to understand their legal obligations. The cases of Strickland v. Washington and Padilla v. Kentucky provide guidelines on how defense attorneys should conduct themselves. According to Strickland v. Washington, a criminal defendant can seek relief for ineffective assistance of counsel only by showing that the counsel's performance was below an objective standard of reasonableness and that there is a reasonable probability that the outcome would have been different with effective counsel. Padilla v. Kentucky outlines the responsibilities of criminal defense attorneys in advising clients on the risk of deportation due to conviction, mandating that attorneys must clearly communicate the potential immigration consequences.
In the business realm, practices like collusion to raise profits are deemed illegal and exploiting gray areas in regulations can be risky. Likewise, in matters of criminal justice, the production, consumption, and transportation of illegal substances are significant areas of criminal activity, with effects that extend to various types of crime.
