The primary suspect in the Kolkata rape and murder case, Sanjay Roy, has been unable to secure legal representation. This has stalled the CBI investigation, as a polygraph test cannot be conducted without the accused’s consent. While Roy can legally refuse the test, the absence of a lawyer raises concerns about his understanding of his rights and the potential consequences of his decision. The court has appointed a legal aid lawyer to represent him, highlighting the importance of legal representation in such cases.
