MUMBAI (AFP) - Anguish turned to anger in Mumbai Wednesday, a week after the deadly attacks, as tens of thousands of people took to the streets to protest against India's political leaders and police. At least 20,000 people turned out to remember the 188 people who died and the more than 300 others injured during the 60-hour orgy of violence that saw two luxury hotels and a number of other sites targeted. But the protesters directed much of their ire towards the government and police, accusing them of failing to protect the public and of ignoring reported intelligence warnings that an attack was imminent. "All these people are taxpayers," said architect Tasneem Jamnagarwala, 32. "But everyday when I walk out of my house I don't know if I will return home safe. There's nothing that the government gives us back." The vast crowd included besuited accountants, Muslim housewives in headscarves and long robes, students in tank-tops and shopkeepers. Many said they had never taken part in a public demonstration before. Several protesters said corruption - long viewed here with resigned apathy - allowed repeated attacks to take place, accusing police and politicians of being more interested in collecting bribes than doing their jobs. Large, vocal crowds chanting "we want justice" gathered around the Gateway of India monument, opposite the Taj Mahal hotel that was one of the sites hit by gunmen. Repeated chants of "We want justice" and "Enough is enough" were heard and there was real anger directed at India's arch-rival Pakistan, amid claims that gunmen based over the border were to blame. "India has borne the brunt of terrorism many times. It's time we should put an end to this," said Maria Merchant, 30, who was accompanying Jamnagarwala. "Action should be taken against the (militant) camps. We know where they train and where they come from." The protest, the largest in recent years and not backed by any particular group, was largely organised by text message, as India's "Maximum City" slowly gets back to normal. The strength of public grievance in India has been seen in the newspapers' letters pages and a C Fore/Hindustan Times survey published Monday. Some 87 per cent of people surveyed thought India was "soft on terrorism", with similar numbers agreeing the country needed tougher politicians and anti-terrorism laws. A majority, 86pc, thought the Mumbai attacks could have been prevented. As foreign intelligence agencies, including the US Federal Bureau of Investigation (FBI), joined their Indian counterparts in the probe, questions have been asked about how much India knew about the attacks and when. US media reports said Washington had warned India in October that hotels and businesses in Mumbai might be targeted by attackers coming from the sea. City police chief Hassan Gafoor admitted Tuesday that they had received warnings after the deadly truck bomb blast at the Marriott hotel in Islamabad on September 20, including that the Taj Mahal hotel could be a target. Meanwhile, Bharat Tandel was on the dockside at the Koliwada fishermen's colony in south Mumbai when he saw the rubber dinghy that would bring carnage to the city motoring towards the shore. "I thought it was strange when I saw them get off the boat and noticed that they were carrying rucksacks," said the bare-foot fisherman. "I asked them what they were doing here and they told me to mind my own business." Minutes later, the daring assault on India's financial capital began. By the time it ended Saturday morning, 188 people had died and 313 others were left injured. "They came in a speedboat at about 9:00 pm. They quickly took off their life jackets and put on their rucksacks," said Parshuram Meher, an official from the local fishing union.
