You did not answer the question. You claimed "Evading conversation is interfering with the officers duty". You were asked how you do square this with an indivduals right to remain silent and against self incrimidation.
Of course, the officer would have to use other methods to determined your ability to operate a motor vehicle or whether you are under the influence, but the question remains: If, as you (wrongly) claim "Evading conversation is interfering with the officers duty" how do you square this a right to remain silent or not incrimidate yourself?
I'll answer for you. You can't. You are wrong and so were the cops in this one.
I've given up responding to this thread. Too much emotion and not enough logic.
