in 1992, george watson looked back at the history of and the island notorious. >>> the evolution of alcatraz has been as spectacular as it has been predictable. it was obvious that sooner or later the military fortress would evolve into a prison fortress and for good reason. the island nded by bay waters that behave like unforgiving open ocean. the island is remote, wind swept, fog shrouded and more than a mile from the mainland. it sounds ugly but to penologist it was beautiful and escape proof. the military thinking prior to the civil warsaw the island as a strategic way to controlling the water. alcatraz was part prison from the beginning. when the first boats arrived, inmates were among them. during the civil war the army transformed the rock into the most heavily armed fortress west of the mississippi. but the giant cannons never fired or shot in anger. the anticipated attack by the south never happened and by war's end alcatraz was obsolete as a force. but as a prison it was still ideal for all but the prisoners. >> well, after the years of civil war this room was converted from a gun

george watson prepared this look back at some of america's transforming inventions. >>> prior to 1900, words like movies, neon, truck, tractor they had no meaning. and what for heaven sake was an aviator. in 1903 the wright brothers sent their aircraft into the air for all of 12 second. with their man flight gave birth to aviation. prior to 1900, there was nothing electric any where. gas lamps lit the homes and streets of urban america and suddenly thomas alba edison made electricity. edison also captured sound in a tube and made concert halls out of people's living rooms. marconi invented the radio. what was this country like in the beginning of the 20th century? this desert flower america blooming for the first time under the glow of the new century's technology. well butch cassidy and the hole in the wall gang were still robbing banks and trains. west of the mississippi and south of the ohio river most americans had never seen so much as the gas street light or indoor plumbing. half of all americans lived on farms or in towns of less than 2,500 people. 100 years ago, horsepower was

and in 2000, ktvu's george watson gave us a look back at the rich history of san francisco's historic and world famous public transit. >> reporter: if it was not so dangerous, this ordinary trip down market would be extraordinarily like key stone cops. the wagons crawl down one side of the street. the horse and buggies start up by the automobiles. bike riders go in and out of traffic. pedestrians don't seem to be worried about the inherent dangers of this fading 19th century transportation in the emerging technology of the coming years. people are dashing behind the electric street cars, dodging horses, wagons, cars, bikes. you can see one century turning into another, and in this adventure, you can also find the cable car. in 1973, british born expert started this line in san francisco. he manufactured wire cable, used it to haul the cars out of mines. he took the next step of adapting cable to street cars. it worked. in 1925, there were 26 cable cars in san francisco, and nothing handles the city's hills better than a cable car. but at 12 minutes past five, the morning of april 18th

watson, thank you very much. reporting from tehran tonight. >>> joining me now, jamie rubin, former assistant secretary of state for public affairs, and michael, former pentagon official for georgebush. great to see both of you. jamie, let me start with you. today prime minister netanyahu saying time to negotiate with iran is over. all they will do is deceive and delay and run up the clock and that they don't even want to define the red line with the united states. they want freedom of action. are they hinting at a preemptive strike without the united states? >> i do think both the israelis and the united states are talking up the military option because to the extent as mayor giuliani said to you i guess last night, the iranians believe that's a possibility. it increases the pressure on iran in combination with sanctions and maybe, just maybe this diplomacy will work that's going to take place perhaps in the coming weeks. i think where the united states and the israelis really are taking a very different view now is on the question of whether it's worthwhile to have the international community, the united states, the european union sit down with iranian representatives under in
