Its ok to be scared.

Who wants criminals or potential criminals in their lives? Anybody? Well, of course not!
Its ok to be scared sometimes. To just take the less heroic path and avoid stuff. Bad stuff. People do bad things to each other. And there are things we don't want to be happening to us. So whenever those things come up, we just avoid the path that leads us there. Is that right? Is that wrong?
If the issue is small, maybe its better to face it. But crime? And really, we don't know what some people can be capable of doing.
Physical well being is important. An athlete may lose his entire life if someone breaks his legs only out of rage. Some accidents can lead to a mental state where we can lose our confidence.
Sometimes its just better to listen to what we're being told. Sometimes its just better to think of safety all the time. Look who you're with. Be aware of who is staring at you. Take care about other people obsessions, it may sometimes affect you. We just never know.
