I've heard more police car sirens in the last two weeks than I have in the last 6 months if not longer. Are they getting more pro-active at apprehending ne'er-do-wells or is there possibly a chance that they put them on to let us know they are around at the moment? There's a lot fewer cars on the road and so it would seem less reason to put the siren on when driving through our village, yet they do so more than ever. Am I imagining it? Anyone else noticed?
