Don't you find it ironic that while the security guard strike has been going on for the past two months, the reports in the news about Cash in Transit robberies have declined measurably. Surely this is proof that most of these robberies occur because of inside information.
I think it is time that the security industry starts cleaning up their act. Start bringing in measures that makes it almost impossible for any person, except the driver, to know where a certain truck is going to be at a certain time. Randomise schedules etc. If this is the case, no one can be threatened to supply the information to the syndicates either, because they don't know, and they can't find out.
