You bring up the name Zimmerman in your post, why was he in the post?
There was no need for him to be brought up if you wanted to say that you don't have to depend on the police to stop crime, you can do it yourself. That means "people" in general can stop crime themselves. You are the one that related Zimmerman to that comment, and I rightly said, don't equate everyone or whoever you were talking about to Zimmerman.
