I went through T3 (domestic) security a few days ago. I'd venture a guess that 80% of the bins that were scanned were diverted to the inspection side where there was a grand total of one person working. It was so backed up that no bins could get through to the clean side. Thankfully mine (eventually) breezed through without a problem. Had it been diverted I'd imagine that would have been another 30 minutes delay at least.
