Not to defend Danilo, but it's common to see that clip without mentioning it was from before all the corruption scandals in his government. Often people want to present this as if he said that afterwards. It's very possible that Danilo himself was not aware of any corruption in his government at the time.
It's an old practice for military officers to do things (kill a certain well known person) and the blame to fall on the president, often times he himself becomes aware of what "he ordered" along with everybody else as the news comes out. Many times it happened to Trujillo despite he was in control with an iron fist, it happened more with Balaguer, etc. Corruption in certain institutions will take place without asking for permission of the president.
