I agree tashadaviesjj. The clue was in the outline of the story - surveillance - so no screaming tyres, no car chases, no running after suspects. The watcher needs patience - not just us - but the actual people doing it. Everyone now wants things sorted out in a couple of days, which doesn't always happen. One thing did amuse me though did none of these folk have curtains/blinds at their windows therefore allowing anyone to be able to see straight into their home.
