yup even brushing your teeth and using mouthwash is not a stymie, often this is viewed as destruction/interference with evidence, if a cop can discover empty aloholic containers.

Brushing your teeth doesn't affect breathalyzer readings at all. Alcoholic mouthwash can give false positives for up to 20 minutes, and cops are supposed to wait and try again for that reason; you've got a good shot at getting it thrown out if they don't.

Here breathlyzers aren't evidence, they're probable cause. To be admissible they either need you to accept the result, or go custodial for a blood test.

around my parts, it would be tampering with evidence even if there is no proof or indicator that evidence of a crime existed, before "tampering" the brushing teeth and mouthwash is simply part of a power commuters hygene routine. in NY for example people use the time spent at traffic lights to do all sorts of things.

That's fucked up, I'm sorry. In most places in the US, cops would ignore it, because it doesn't do anything. Breathalyzers detect metabolized alcohol vapor from your lungs; nothing you can put in your mouth will stop that as long as there's alcohol in your bloodstream and you're still breathing.

oh dont be sorry its not your fault and interjections are valid, just to get things on track with the thread, this is about circumventing an authorities ability to detect an offence, and some authorities will assume innoccuous behaviour is evidence probable cause or reasonable suspicion, basically where im sitting, any circumstance you create that causes an investigation to go off script, can be interference if you intended to do it regardless of what you are trying to accomplish.
