Green Granite, I assume that if an aircraft is forced to return to stand following such an accusation, a wait is incurred for steps/a stand/a jetty etc then plod strolling on deciding there isnt enough cause to administer such a test, patting the guy on the back and letting them on their merry way isnt sufficient. Would the falsely accused then be in a fit state to operate? Would the crew now be in hours? Has the destination got a curfew? Is it wise for any company to allow the falsely accused to operate and assume if anything totally unconnected occurs the red tops would not have a field day?
It appears in such an incident the police have no choice therefore to administer the test. I accept that. It therefore makes it even more important to ascertain why the accusation has been made and if any fault can be found the accuser is dealt with severly, it is not an acceptable defence to claim one was acting in the interests of the passengers and using it as a 'get out of jail card.'
