Some people say, "the police have done the right thing in that hurry situation, because they cannot put hundreds of lifes at stake, and the man may have done something very wrong, that's why he ran away from police."
If I were him, I would also run away from them. Why? because the police looked and acted same way terrorists and gangsters did. With fear of bomb, the brazilian man just fled away, simple explanation. At that time, people around him also fled like hell, and why didn't the police kill all the runners? There is no guarantee that the man stood still would save his life, because those police had decided the man's faith already. They clearly intended to kill the man.
