Edinburgh agrees with London: Better to Swallow than Spit
In order to reduce the high incidence of subway employees being spat upon, at the rate of 100 cases per year apparently, London authorities last year turned to simple DNA kits containing latex gloves, swabs, and an evidence bag. Bus drivers and now traffic wardens of Edinburgh, Scotland have also taken up the DNA kits to deal with their own spitting menace.
