Attack on the congress

I seriously condemn the attack made on the Brazilian congress by dissident MST (movement of the landless) dissident called MLST (movement for the freedom of the landless). Nevertheless, I think people should pay attention to this fact.
There is a global discontentment in this country in relation to the Congress. After all, how many politicians involved in serious corruption scandals have been forgiven by their own peers! >500 people participated in that revolt, and this global sentiment is present throughout. For example, how many people have jokingly said that: we should bomb everybody in Brasilia... even though of course, no one actually wants to do harm, the feeling is there. And the revolt is a symptom of it.
In the same manner that the attack on the world trade center in 2001 is that there is discontentment in the whole world, and maybe specially in islam in regards to america's foreign policy. The least we should do is open our eyes and try to see what is really going on.
