My condolences for your loss.
Simultaneously, I don't understand your post. The second paragraph states "I have been told from very well placed sources in the US Intelligence community this is probably a hit." But then the rest of your post rails against the SF crime problem in general, finishing with "And now a good friend is fucking dead." Starting off by saying it was likely a hit would appear to indicate that SF's general crime problems (as bad as they may be) are largely irrelevant to this particular case.
