I like the examples of people at least doing something such as challenging the aggressor to stop, staying on scene, and calling the police. This type of intervention seems to work alot of the time. Yes, the agressor could turn his attention to you but if you armed, you have alot more options to deal with it. The key thing here is to do something to stop the obvious unlawful assault on a person instead of just walking away and maybe making the 911 call as you leave. Sometimes all a thug needs to see is someone is watching and not backing away. Doing this amounts to courage. Some people act courageously and some don't. They'll explain it away as "I don't want to get involved or its too risky." But what it amounts to is a lack of courage in that particular situation.
A fight is a fight. An under cover officer making an arrest of a resisting suspect will look like a fight or an arrest. It's best to sit back and be a good witness in those types of situations. Those situations won't be a man kicking a defenseless person in the head multiple times to the point of near death. We've heard it a million times, "All that is necessary for the triumph of evil is that good men doing nothing." Prepare your mind, train yourself, use sound judgment, and follow the right post incident procedure and I believe you'll be just fine when the time comes for a good man to do something.
