The failure to answer questions posed by the police, in and of itself, does not provide probable cause to arrest you.  Other relevant conduct or circumstances may lead an officer to conduct an investigative stop.  Keep in mind that section 901.36, Florida Statutes, provides that giving false information to the police during a valid investigative stop or during an arrest is a misdemeanor.   Running from or fleeing the police, without some additional suspicion that a crime has been committed and that you are the person that committed the crime, will not be sufficient probable cause to sustain an arrest. However, Florida’s Uniform Traffic Control Law provides that under certain circumstances, it is unlawful to flee or to willfully fail or refuse to comply with an order of a law enforcement officer.  §§316.072 and 316.1935, Fla. Stats.  In reality, police officers have to make split-second decisions while investigating allegations that a crime has been committed.  Therefore, when a person runs from or flees the police in any way, it is often interpreted to mean the person has something to hide, which may cause the police to be more interested in asking that person questions regarding the allegations that a crime has been committed.
