If an individual does not consent, the officer must either release the person or detain the person and attempt to get a warrant. The fact that an individual refuses to consent does not give the officer grounds to obtain a warrant. I retain my Fourth Amendment rights and all other rights under the United States Constitution. I will say nothing until my attorney is present. No matter what a law enforcement officer threatens or promises, it is always better to refuse to consent to a search.
Individuals have the right to have an attorney present during questioning.
Only a qualified attorney can ensure that the suspect or defendant does not say anything damaging. From the time a law enforcement officer approaches, it is wise to remain calm and not arouse suspicion. Law enforcement officers are trained to create the impression that their suspects are obliged to stay. If not, I really need to get going. Have a nice day.
