Pooches: Is it Better Not to Know?

Lately I've been wondering whether it really is that good of a thing to have so much information readily available.
See, I'm part of a Neighborhood Watch Facebook page where the community members keep everyone aware by posting about any vandalism, break-in's or general weirdness in the neighborhood.
There are thousands of people on the page.
So we hear about a lot of vandalism, break-in's and general weirdness.
The funny thing is, so many people take these accounts as an example of how the neighborhood is getting worse.
When really, the neighborhood has been getting tons better, it's just that we now have the connection to more people to hear about every single incident that we never even would have known about before.

Which is also what has been happening with my dog information.
Now that we have so many ways to connect and gather information, I get to hear so many scary stories as people share about what has happened with other dogs.
About dogs getting stolen from backyards.
About poison treats people encounter on walks.
And about sudden cases of glaucoma developing into blindness, which now has had me scurrying to the vet any time bug-eyed Miss M squints at me funny.

I too want to share when I hear about these things because it really could help us prevent misfortune for another family.
Though at the same time, I feel prone to "Over-caution Syndrome" where I'm starting to become neurotic about what should be simple things, and I wonder if my vet visits are really warranted, or just over-reacting.

So, what does everyone think: Is it a good thing that we have so much information at our disposal? Or have others become as neurotic as me and it's better just not to know?

And I am completely guilty of this too. 
And here.
Oh yeah, and this one too.
