A very important thing when you're accused or charged with a crime is knowing your rights. Many aspects of law enforcement are geared toward gaining a confession, or persuading the accused to admit to wrongdoing.
Law enforcement officers are even trained to ask specific questions to gain information about an occurrence which, if answered, may incriminate you.
Knowing your rights, and that you don't have to speak with law enforcement, is important. Further, an attorney who can protect your rights is the most important. Koller & Meador effectively handles traffic citations and misdemeanors to complex felonies.
