Supposing that you have an outstanding warrant in Arizona, do not panic, and do not automatically assume the worst. Handle the warrant; attempting to run from a warrant is a big mistake. Airports, bus stations, railroad stations, etc maintain listings of active warrants which hinder an individual from leaving the country.
Do not abruptly turn yourself in on the warrant. Speak to a legal representative or, if not, establish plans before surrendering..
Additionally, an attorney might find out that it might not be required for you to surrender and get you a quick arraignment, which can help decrease the amount of time you may spend in jail. In other words, a legal professional knows the particulars of the legal circumstance you are in.
