Monitoring rubbish; LETTERS.
This is because I live in sheltered accommodation in a block of 25 flats and a guest room. We all put our own rubbish in plastic bags that are then dumped in bins in a communal refuse room. Cardiff, Merthyr and Swansea have tower blocks and they probably have refuse chutes leading into containers for bulk disposal.
Thus, if people in flats are immune from being spied upon, why should the rest be monitored? GARETH D EVANS Herbert Street, Treorchy
