Summary
Texas v. Cobb is important for officers and detectives because it confirms that the Sixth Amendment right to counsel is offense-specific. If a person has been charged and has counsel on one offense, that does not automatically prevent officers from questioning the person about a separate, uncharged offense.
Legal Issue
The issue in Texas v. Cobb was whether the Sixth Amendment right to counsel, once it attaches to a charged offense, also automatically protects a suspect from police questioning about other uncharged crimes that are factually connected to the charged case. In plain English, the question was this: if a suspect has a lawyer for one charged crime, can officers question him about a different but related crime after giving Miranda warnings and getting a waiver, or does the lawyer’s involvement in the first case block questioning about the second case?
Holding
The Supreme Court reversed the Texas Court of Criminal Appeals. The Court held that the Sixth Amendment right to counsel is offense-specific. That means the right attaches to the particular offense that has been formally charged, not automatically to every other crime that may be factually connected. The Court rejected the “closely related factually” test used by the Texas court. Instead, the practical rule is that the Sixth Amendment right to counsel extends to the charged offense and to any uncharged offense that would be considered the same offense under the Blockburger test. Under that test, courts compare the legal elements of the offenses, not just the facts. If each offense requires proof of an element the other does not, they are treated as separate offenses. Because Cobb had been charged with burglary, his Sixth Amendment right to counsel had attached to the burglary charge. But the Supreme Court held that the right did not automatically bar police from questioning him about the separate murder offenses. His confession after Miranda warnings was not suppressed on the ground used by the Texas court.

Impact for Officers
Texas v. Cobb is important for officers and detectives because it confirms that the Sixth Amendment right to counsel is offense-specific. If a person has been charged and has counsel on one offense, that does not automatically prevent officers from questioning the person about a separate, uncharged offense. The key caution is that “related facts” are not enough by themselves. Two crimes may arise from the same event, involve the same victim, or be part of the same investigation, but the Sixth Amendment analysis turns on whether they are legally the same offense under the elements-based Blockburger test. Officers should not assume that factual overlap alone creates a Sixth Amendment bar, but they also should not assume every related offense is separate without legal review. For police practice, the safest approach is to identify exactly what offense has already been charged and what offense officers want to discuss. If questioning will concern the charged offense, officers must recognize that the Sixth Amendment right has attached. If questioning will concern a different offense, Texas v. Cobb allows questioning only if that offense is legally separate and the suspect validly waives applicable rights, including Miranda rights when custodial interrogation is involved. This case does not eliminate Miranda. It also does not give officers permission to deliberately question a represented defendant about the charged case outside counsel. Its practical point is narrower: having a lawyer on one charged offense does not, by itself, create a blanket prohibition on questioning about all factually related uncharged offenses.
