Almost ten weeks after two hostages and gunman Man Haron Monis were killed in a siege on a Sydney café, Australian Prime Minister Tony Abbott has hinted at tighter immigration laws.<br /><br /> Following the release of the government’s first report into the attack, the leader laid blame at the door of the country’s legal system.<br /><br /> “Plainly, this monster should not have been in our community. He shouldn’t have been allowed into the country. He shouldn’t have been out on bail. He shouldn’t have been with a gun and he shouldn’t have become radicalised. Plainly, all of these things should not have happened.<br /><br /> He said legislation had “let the country down” by failing to realise hostage-taker Man Haron Monis was dangerous.<br /><br /> Members of the public made 18 phone calls over the nature of his Facebook posts in the week preceding the siege, but agencies found he was not an imminent threat.<br /><br /> Haron Monis travelled to Australia in 1996 and sought asylum a month later, after which he was granted citizenship.
