It's not so much people in these type of jobs that worry me so much as those who work in 'invisible' jobs. The chaps who work in the sewers, school caretakers, taxi drivers,the utility workers...not sure what you call them but the ones who we see everyday but take no notice of at all so can go practically anywhere without suspicion. Postmen, waiters,bus drivers that sort of job. How often do you notice them in the street or are they basically invisible? have you been in the back of a taxi chatting with your mates and totally forgotten the driver was there, could you recognise him again? would you take much notice of a postman walking down the street, they go into every building as do delivery drivers, normal evryday business but the access they have to buildings is amazing, people just don't take any notice if someone looks as if they should be there.
We have a joke that you can walk around all day where we work doing nothing as long as you have a file or some papers in your hand and look busy, great way to waste a whole shift but it's true.
As we learned with the IRA the best defence against terrorists is the people being vigilant, noticing what should be there and what shouldn't and reporting it asap. Not to get paranoid and becoming snitches btw but use common sense and stay vigilant. It's often stated as being needed for SD but it's also useful for anti terrorism.
