Man Kick Young Kid Without Reason, His Father Delivers Instant Justice

Some people are not really smart. Security cameras in a fast-food restaurant captured the moment when a boy approached the counter. But his vividness was obviously too much for another man waiting on the opposide side - he kicked the innocent little one without any reason.

After a boy, there was his father, and his blood was blown off by the scene. Without questions, he punched man so he would know that he can't touch his child. Did this Dad did the right thing?
