and with legs six feet long, it doesn't take much effort for the giraffe to move across the african savannah. flightless birds, like this ostrich, use their strong legs to escape predators and deliver lethal kicks. how would you like to get a face full of these feet? kangaroos don't run, they hop, which works quite well. this springy marsupial can cover 20 feet in a single bound. in southeast asia, the orangutan's short legs make walking a bit cumbersome. but with a wingspan that stretches seven feet, it can swing through trees with the greatest of ease. we humans aren't built for tree climbing, but our long, powerful legs enable us to run great distances. and sprint up to 27 miles per hour. we can also leap more than three times our height. but how does our ability to run and jump compare to other animals? well there's one sure fire way to find out. it's time for our animal science experiment of the week. our experiment features two participants. one is a college long jumper. the other is a belgian shepherd dog named rocket. each will sprint down the runway and then leap as far as possible

savannah, good morning. fund-raiser in the bahamas, whose membership includes thousands of mostly african-american women in businesshe end, despite the growing scandal. looking relaxed on stage, bill cosby made no mention thursday night of the sexual assault allegations. instead, sticking to his comedy routine, including stories about his childhood. >> i'm here to have a good time and laugh at what this guy is being paid to do, make me laugh. >> reporter: still others in the crowd, several hundred people, thought his silence has dragged on too long. >> if it didn't happen, tell us it didn't happen. if it did happen, be sorrowful about it and be apologetic and let us know. >> reporter: on thursday, high point university removed cosby from its board of advisers. an arizona casino canceled a performance in february. the allegations against the sitcom star have swirled for a decade but have intensified in the last month as several more women have come forward. >> he stood before me and he -- in his hand he had two big, large white pills and he said take these. my next memory is feeling drugged and him having sex with m

savannah, the system needs to be indicted. this system is completely unfair to the citizens, especially african-american and minority citizens when you have police-involved shootings. this system, over and over again, exonerates police officers for killing young people of color. >> let me ask you this. the prosecutor said i put all the evidence i had before the grand jurors and i let the grand jurors decide. is there something wrong with him proceeding in that way? >> you know, he said he did it this way because he thought it was fair. he didn't recommend any charges or anything. just put all the evidence out there and let's just be fair to everybody. and this is different than what i've ever seen in my 20 years of practicing law. so the question becomes, savannah, if for 28 years he has been prosecutor for the grand juries, he didn't do it this way. was he being unfair to them? why change the rules now when it's our children lying on the ground? we want the same justice. we want equal justice that you do for everybody else. don't change the rules on our children. >> benjamin crump, wish we had more time. thank you, sir, for bein
