In the UK, breath alcohol testing has been used for over 30 years. Traditionally, breath testing was conducted at the roadside and was backed up by a secondary urine or blood test, but more recently police stations are equipped with a more accurate breath testing machine which has been standing up in court without issue for several years.
Breath is perfectly valid as a matrix for testing, so their complaint can only be in relation specifically to the equipment itself... but what a can of worms to open - in my opinion, drinking and driving costs lives, so I hope their attempts to undermine the testing process doesn't broadcast the wrong message.
