Intimidation should stop. One day or another, we've all been part of an intimidation process, being either the victim, the bully or the witness. More often then not, witnesses aren't doing anything because they feel powerless or because they are afraid to be the next victim. But, by watching the scene happen, you only feed the bully of even more power and more confidence which will make the bully continue.
What we should do as a spectator is to act. We need to act. We need to stop these people because intimidation is a hole in the society. In order to stop them, you have to tell them to stop. Don't be afraid. They won't hurt you, but by using the right words, you may actually make them realise what they've done. You may think that alone you have no power against those people, but that's where you are wrong. If only One person would have the courage to tell the truth, things would definitely change.
This is why intimidation should be stopped. Because people get hurt everyday, for no reason, and it hasn't stopped yet. But it will soon, if we decide to make things change, one by one.
