Dont Blow Dont walk Dont Comply.
First don't drink and drive, but if you do, taking tests is GIVING POLICE EVIDENCE. You are not required to do this and he thinks it is so stupid that citizens don't know this yet.
Simply say, 'If I am under arrest please do so. If I am not, let me go."
If they arrest you, don't blow in the breathalizer. Just get a good lawyer.
