Please IGNORE the advice given you by kxaltli! OMG, I do not know how to stress this enough--DO NOT EVER SPEAK TO THE POLICE WITHOUT FIRST CONTACTING AN ATTORNEY! NEVER. Even if you're innocent. No matter what the police officer tells you, NO MATTER WHAT HE SAYS, never EVER cooperate with the police without first contacting an attorney.
First of all, if the police had enough evidence to charge you with a crime, THEY ALREADY WOULD HAVE. You'd have received a summons or have been arrested. The only reason they want to talk to you so bad is because they do not have enough evidence to charge you with a crime, and they are hoping you will incriminate yourself. THAT IS THE ONLY REASON. Police are very good at making people say what they want to hear--do not attempt to outsmart them, do not engage in any conversation with them whatsoever.
The idea that not cooperating with the police will somehow hurt you is a BOGUS, absolute absurdity perpetuated by the police themselves. Keep in mind the police have absolutely NO influence in whether or not you are guilty or innocent at your trial, nor does cooperating with the police or not cooperating with them have any bearing on your possible sentence if found guilty. They will make many promises--promises they cannot keep. The notion that if you have nothing to hide, you should cooperate is BOGUS--the police obviously think you're guilty, they've made up their minds, but they don't have enough to charge you yet, and the only reason they want you to talk is to get a confession out of you, or force you to incriminate yourself. DO NOT FALL FOR IT.
Let me stress again--IT DOES NOT MATTER HOW YOU "look"--the police can think you are guilty till they are blue in the face, it doesn't make it so. COOPERATING NEVER HELPS YOU, it CANNOT HELP YOU, you are only giving them additional evidence to use against you. DO NOT COOPERATE WITH THE POLICE. People who have nothing to hide OFTEN HIDE ANYWAY, why? Because it's your right. The police do not have the right to force your confession or force information out of you or compell you to implicate yourself. Do not listen to the advice given you by most people here because they falsely believe the lines straight out of the police playbook--the police count on the public's ignorance of their rights to nab them. Do not be another statistic.
