The protest reminds of the days when I was still a student activist. The only difference is that there are more people in a student rally than what I witnessed here. It was few and not enough to command political majority.
Also in a few shots of tear gas, the protesters dispersed all over the place, making the rally short.
If it was in Manila, most likely the tear gas will be hurdled back to the police and protesters will stay until more people have come to join.
To have a successful rally, the people should not only have the conviction but also the ideology to push thru a revolutionary change. Which I do not think this people has what it takes to be an activist.
