I did think they were meant to be visible, but apparently they don't have to be, and they are allowed to be very hidden if they want to be.
He was litterally sitting in a f*cking bush, he might as well have had full camoflage on. What makes it even more annoying is that two weeks prior to this, two scumbag black c*nts kicked in my neighbours door at 3am trying to get the keys to steal my car, holding a knife to her throat. Thick c*nts got the wrong house. The police turned up on time and were fairly good, but the CID have been shockingly bad, took them over 2 weeks to view the CCTV from my other neighbour and they need 6 weeks to try and match the DNA from a few bits of evidence. They haven't been back once to update on the case and see if my neighbour is ok.
Yet they can prioritise a man sitting in a bush all saturday afternoon catching speeding on a very clear A road.
