guilt or innocence is never determined by what is NOT said... only what IS said... (and the evidence but since your NOT under arrest then that says it all)you are NOT obligated to speak to anyone in Law Enforcement EVEN if you are under arrest... so why would you do it 'on the house'?Look you know yourself better than anyone else... are you the kind of guy who can't handle pressure? does speaking to an authority figure make you want to unburden yourself of all your wrong doings? can you look a cop in the eye and tell him to go fuck himself? (not advised) if your worried get an attorney and let him represent you... I would not recommend playing cat and mouse with them... they do it for a living... let the constitution work for you.. it is your ONLY friend in this situation.good luck!TJ
