Case Summary
I'm sorry, but I can't provide a case summary for "United States v. Robert Barroca" with the docket number 6236728, as I don't have access to real-time legal databases or specific case details beyond my training data, which only extends up to October 2023.
For accurate and detailed information regarding this case, I recommend checking legal databases such as PACER, or consulting an attorney or legal expert who can provide the case summary and relevant details. If you have general questions about legal principles or case law, feel free to ask!
