and i knew that he was not breathing at that point. and it was just a matter of time before he would succumb. when i was doing this, i asked the people standing there, i said, hey. if you want to help, give me a hand. >> after more than a minute into taping, the woman capturing all this calls 911. >> i'm in the city of boston and there's a cop fighting a guy and he could sure use some backup. >> by that time, the eyewitnesss from the street grab all four limbs, while the sergeant handcuffs the man, who is later identified as ruben delgado.$gm sergeant colombo, unharmed, then realizes the brawl's been caught on tape. the tape is invaluable. it's more than enough evidence for a judge to sentence delgado to a two-year prison term. as we've just seen, some people resist arrest by trying to fight off a police officer. other criminals try to fool cops with a good story. you've got to see this next encounter to believe it. listen closely and you be the judge. pollock, louisiana, april 5th,
