The police are allowed to lie or trick you to give a statement, but not to use force, threats, false promises, or coercion. If they use those tactics and the judge believes the testimony of the defendant he might rule that the statement was not given voluntarily and it can be held inadmissible at trial. Most defendants are easily manipulated unto giving a confession or giving information concerning co-defendants and it will not be considered coercion. Innocent people do not confess and smart people will tell the police that they are not going to talk without a lawyer. Not every "threat" is coercion and not every statement is going to be suppressed, it depends on the circumstances. Remember, "Fish Only Get Caught When They Open Their Mouths"
