Play 1 as well <| sep |> Nah , you ' re confused . I fully agree with the right to a vigorous defense in this country . That said , nobody is entitled to receive big piles of money to pay a private defense attorney to try to escape conviction for their heinous crimes .

If the advancing blade half of the disc is creating lift and the retreating blade is not , that would be like only having a wing on the right side of your airplane you wouldn ' t be able to fly straight and level very well .
