I've had one of each. Firstly, about five years ago, I got up at about 8 o'clock one morning and noticed a Transit-style van parked on the layby outside with what looked like two or three people sitting in the front. So far, so normal. Then I noticed the new ladders on the van's roof rack, as if it were a tradesman's van. The van was as clean as a whistle, in excellent shape so a bit too smart-looking. Then I noticed it had windows along the side, not just tinted but blacked-out. It was still there when I went out for the morning and I thought nothing more of it. When it was still there when I got home again at about 1pm I thought it was just a bit too odd for comfort so I sneaked out to get the registration (occupants still inside) and phoned the non-emergency police number from back inside. The operator was brilliant, very calm and clear and asked a fair few questions. She said they would be back in touch whatever the situation turned out to be. About five minutes later, the same police operator phoned back to assure me there was nothing to worry about but she wouldn't tell me why the van was there or what else was going on. I think I must have stumbled on to something though because, just a few minutes later, the van was driven away. Obviously a surveillance vehicle of some sort. If I spoiled Operation Britannica for MI6 or Special Branch, I am truly sorry ! But they were just standing out a little too much.
Secondly, when I was still at the family home, one dark night I noticed a youth skulking around outside the next-door neighbour's house. I didn't recognise him (dark night didn't help) and guessed he was up to no good so I dialled 999 straight away. In the meantime I went downstairs where my M&D were watching television, turned the sound down and told them the situation in hushed tones. Police turned up in a matter of minutes with an incredibly bright flashlight and shone it around next door's driveway and front garden. No sign of our hero by this time. The neighbours came to the door and the constable told them what was going on. Anyways, it turns out the youth in question was their grandson who was staying with them at the time. Probably lost his key. They were very grateful for my vigilance nevertheless but their grandson was probably less impressed! Great police response
