CHARLIE STERNE, of Britannia Avenue, Dartmouth, writes: I am pleased to note that the Harbour Authority is taking seriously the possibility of an attack by jihadi terrorists in the near future. It has recently installed ­cameras inside and outside the harbour office on the South Embankment. Access to Hoodown has long been a no-no, so perhaps before long we may see a Dart Harbour Navigation Authority armed response rib patrolling the river. Whatever next?
