There is some relief in learning that a homeless person didn't commit this crime. However, the overall crime situation in SF, and other parts of the Bay, is still crazy... and I think that is the genesis of the 2600+ comment thread on the crime and homeless situation. SF crime IS A PROBLEM that is not being adequately addressed. So much so that folks assumed Bob was probably killed by a crazy drug addict or something. While wrong in this case, it was a reasonable first guess. And the conversation and flood of comment on the topic of crime flooded in from there.
