Les Aspin House of Representatives, Washington, D.C. 20515 Dear Congressman Aspin-- This is to say how keenly I support your effort to regulate the abuse of telephone privacy. I would appreciate receiving a copy of the bill HR 13267, and other information on its legislative status. This is not a peripheral issue of minor personal irritation. The telephone system is central to the whole network of inter-personal communication in our culture. We will see many further technical advances that will doubtless reduce its costs -- and make it ever more attractive to unsolicited intrusions. It is insufferable that this instrument of personal conversation should be abused to the extent it already has; and if unchecked, this trend will surely become ever worse, Even unlisted numbers are not a sure protection. And before long, telephone salesmen will have recourse to computer-mechanized dialing, which can automatically scan through every possible telephone number, whether in the directory or not, in the search for sales prospects. XS I may have some technical’ comments, if I may have the opportunity to peruse your bill; but I have no doubt of be. an enthusiastic supporter of your initiativ Sincerely yours, \ a Joshua Lederberg LT.
