National police chief Chakthip Chaijinda on Thursday said the police received a warning about the attack just one hour before. Pol Gen Chakthip still owes the public an explanation over what security officials did during this window period. Tuesday's bomb attack raises questions about the effectiveness of security measures as it it's evident the situation has not been improved even though financial and personnel resources have been increasingly mobilised. The government needs to change its military mindset when it comes to security measures. Effectiveness of budget spending and efficiency in security measures need to be scrutinised and guaranteed along with the peace dialogue.
