Police in Bicester set up a drug testing station in a pub, and swabbed the palms of every customer before they were allowed to enter. The swab was checked for drug residue. Anyone who tested positive was searched on the spot for possession of drugs. 150 people submitted to the test.
The police explained that it was part of a crackdown on violent street crime.
That is fucked up. I would refuse the test and never return to that establishment again.
