I don't disagree with that. It's the "it's not my responsibility" type thinking with regard to community safety and security. I wouldn't trade my life, or put it in danger, not knowingly anyway, over property, mine or anybody's. However, I think people, like Zimmerman, who do take an interest, and responsibility for their community are to be commended. Are they all the type we'd want doing it? Maybe not. But overall, the world would be a better place if we all chipped in to "watch over" our communities.
I personally agree with that, but with that being said, I still don't expect anyone to watch over my property. While it's the
nice thing to do, and such actions would make our communities better places, it's not anyone else's responsibility to safeguard my property or my life. I think there's a difference between what one thinks they
should do out of kindness/morality/community betterment, and what one thinks they
must do out of self-preservation.
In theory, if we all took responsibility for our own stuff, then the community would be "watched over." It's when one person fails to take responsibility for their own stuff that we then require someone to watch over them. In reality, we can't be with our property at all times, and so this is why neighbors
should watch out for each other to a reasonable degree.
