Security concerns and cricket

In its explanation for postponement of the tour of Bangladesh by the Australian cricket team due to begin early this month, the cricket authority there, Cricket Australia (CA), pointed out security concerns. Both the Australian Security Intelligence Organisation (ASIO) and the Department of Foreign Affairs and Trade (DFAT) alerted CA of 'credible risk' to Australians in Bangladesh and so advised not to proceed with the tour. A three-member delegation that CA sent to Bangladesh for assessment of the situation also agreed with the ASIO and DFAT. When the delegation was in Dhaka, an Italian aid worker was shot dead, of which the Islamic State (IS) claimed responsibility. Following this a few western embassies also issued red alert on travel in this country by their nationals.
Protestation by the Bangladesh Cricket Control Board (BCB) and the government that they would provide the highest security reserved for the very very important persons (VVIPs) for the Australian team was of no use. The tour has fallen through. Although, a couple of former Aussie cricket captains, the team coach and even the newly capped captain have expressed their deep disappointment at the postponement, this is cold comfort for Bangladesh. The rise of Bangladesh as a cricket power is now a fact and following the loss of Ashes to England, Australian cricket has gone through a turbulent time. Heads including that of Michael Clarke and a number of senior players have rolled and to add to the woes, a few have been left to rest and injuries to others have only exacerbated the matter.
Teams like Pakistan, India and South Africa visited Bangladesh this year. The triumph of the Tigers over all three teams in the One Day Internationals (ODIs) is a testimony to the fact that it is resurgence of a team that had nothing comparable to the feats in the past. Can it be that the Aussies looked for a pretext in order to skip the visit?
Coming to the issue of security, it would not be out of place to refer to the fact that Australia itself is incapable of protecting its members of the law enforcement agency and citizens and that too in front of police headquarters. If a gunman can kill a policeman and then target another officer right in front of the agency's headquarters, the security is awfully exposed.  It appears the security problem is more with the Australians in Australia than with the Australians in Bangladesh.
If the murder of an Italian citizen has prompted the CA delegation to cancel the tour, what would have been its decision if this did not take place? Accepted that the involvement of the IS in this act of murder is convincing. How can the agency rule out link of the attack in its backyard to terrorism well before investigation? If it happens in Bangladesh, it has to be linked to terrorist organisation is a foregone conclusion. This is double standard. Is not the threat of IS more potent in Western countries where youth, usually school and college students, leave their countries to join the terror group in Syria and Iraq?
Then nine persons were killed in shooting at a college in Oregon, the United States of America this past week. And it is not for the first time that such an ugly incident has taken place. If schools, colleges and universities witness such frenzied murders from time to time, how does the country rank in terms of security? Governments around the world will not issue red alert on visits to Australia and the USA after the two incidents. Will they? Returning to Aussie tour, it may be more a case of cricket diplomacy than security concerns.
