Kieran, all the "assailant" did was display a weapon, which he then dropped. A "lunge" in one man's eyes might be a "drunken stagger towards" in another man's eyes. Other than that it was a mutual combat situation, and San Francisco doesn't have room for convicted criminals in thier jails, let alone drunk transients who have outstanding warrants for non payment of child support. Mr.fish screwed up because he made eye contact with a derelict- he shoulda kept walking. Don't blame the SFPD for a situation that exists because the City Government does whatever it can do to accomidate homeless derelects within the city limits.
If a city wants to get rid of this element of society all they have to do is quit paying them for being pathetic, stop funneling tax money to homeless shelters, vigerously enforce code violations against soup kitchens and homeless shelters, bust transients for deficating on doorways and shooting dope in public and occasionally beat the living crap out of posers who pretend to be crazier than they really are. Sorry, but I hate derelects and wish them all dead. They are a drain on society and I cannot express my naked hatred for these pathetic pieces of toejam who hold up cardboard signs as they waltz through traffic, pretending to be a vet or whatever and needing of a handout.
Sorry, but people who choose to be the dregs of society deserve no compassion or respect, much less a paycheck and a free meal. As far as I am concerned this element of society chooses to be what they are and should be ignored to revel in thier filth, not given a paycheck.
mr.fish, invest in a can of industrial strength pepper spray like they use for bears and the next time some amazinhunk confronts you spray him in the face and keep on walking. I'm sorry your beautiful city has been defecated upon by this scourge.
