mr. mallory -- okay, i'll finish up -- mr. mallory who works for the port of san francisco -- these garbage cans have cut drastically the amount of rats and scavenging in the garbage cans, that's what we need, thank you. >> hello, my name is steven te in everyone nis and i second what -- tennis what this gentleman just said. for some reason someone came up with the bright idea of taking away the trash receptacles on our local streets and it just made things worse. i would love to sit down for five minutes with the person who came up with that idea. i think what would really help is as this gentleman said that we get the trash back off the streets. thank you very much. >> hi, just it seems that we're spending about a quarter of a billion dollars each year on 15,000 homeless, and another quarter of a billion per year -- actually half a billion dollars per year on 55,000 students. it seems that we're spending 50% more per head for the homeless and i'm just wondering why neither population is really like doing very well for that ki
