The most common constitutional issues associated with sex crime cases relate to statements allegedly made by the person who is arrested or otherwise charged. Many of these issues are litigated under the Fifth Amendment of the United States Constitution. There are also issues under the Fourth Amendment—which tend to focus on the search and seizure of cellphones—because electronic evidence is often sought, seized, and used in trials in these cases. Understanding how DC sex crimes are handled, and how charges might be impacted by constitutional issues, is important for anyone who is accused.
