How do you people out there feel about the Amazing Race eposide from last night?

I am not upset about the Cowboys getting the boot last night and on paper no rules were broken but The Amazing Race should be embarred for what 2 or 3 of the teams got away with last night. How is it that if you're suppose to go back and start over or somebody just blatantly tells you the correct answer or if somebody loses their map and are allowed to finish without going all the way back and starting over and you don't penalized any way shape or form. You can't fault the contestants for anything but that just looks real bad on the show.
