Theres only 2 problems with bringing back the dinosaurs.
One, successfully assembling the genetic code (see the book The Lost World [AFTER reading the first one!!!]).
Two, they will never be free.
No matter how much I want a Jurassic Park, I say it shouldnt happen. Why? Simply because keeping animals in captivity is wrong.
The number 2 problem wouldn't be a problem to them because they obviously not think it as problem. Heck they will even clone the neanderthal. Those kind of morality is not on those scientist.
