This kind of rally are just for show. They are being paid to do those kind of moves. It was a part of the big plan which is to overthrow the current President of the Republic of the Philippines. But this kind of rally is not being listened to by the majority of the population since the people are tired of this lies.
Give it a few more months and almost every person in the Philippines will know or be related to someone who's been murdered because of 'drugs' with the full blessing of the state, and in certain cases the state is paying people to murder others.
That's a few notches up from being lied to by your local newspaper.
As it is not scary sounds, but very many residents of the Philippines now really supports such action Duterte. In the history of mankind there have been cases when dictators come with the full support of the population, and then beginning suffering residents of that state, and then other countries. For Example, Hitler. Now Putin it copies and it is much worse than Duterte.
