Listen. I know I talk about this all the time. I know I tell you "I'm a DUI attorney, trust me when I say this." And I know that very few people, if any really listen to what I say.
But I can't help from talking about this again. Do not talk to the cops. Ever. They are not your friend. They are not trying to help you. They are trying to put you in jail. And they should be treated like someone that can and will hurt you as soon as they feel like they have reason to do so.
For example, cops are trained to, when they have a "hunch" and know that they can't legally go and investigate, to make contact with the person in a "casual encounter." What is a casual encounter? It's when the cops come up and just start chatting you up. Ask any DUI attorney and they'll tell you this is where the cops start building their case against you.
So, how can you fight this? How can you keep the cops from sending you to jail? How can you keep the cops from forcing you to hire a DUI lawyer to help you out of this jam? Easy. Don't give them any reason to arrest you. And, contrary to popular belief, not answering a cop's question does not provide they reason the cops need to arrest you.
Next time the cops come up to you and start asking you questions, just tell them, politely, that you don't want to talk. If they persist, tell, them, again, nicely, that you want nothing to do with them and if they have questions they can talk to your criminal lawyer. That's the safe way to stay out of trouble.
