No.

I support this notion. The human race could do with a good pruning.

Yes. Jurassic Park is one of my favourite movies. I want real dinosaurs.

They should - but it's so far away that we can't even begin to answer this question. The ability to actually  bring an extinct animal back through preserved DNA is extremely unlikely. They're trying to do it with Tasmanian Tigers, but even that's looking hopeless - there's just too little intact DNA. With dinosaurs, it would be even worse. Don't get me wrong, DNA's a tough molecule (as molecules go), but I'd wager it's impossible to actually get any useful Dinosaur DNA without some kind of time-travel (which I believe is impossible). Raw DNA starts to degrade if it's not chilled constantly, and if it's just left in the environment, it would very quickly break down. Plus, there was an ice age between the Dinosaur Era and the Current Era, and if DNA, in a solution, gets frozen, ice crystals shatter the structure to all hell. 
 
If we somehow had the technology, and we miraculously found a complete sequence of a Dinosaur, then yes we should - because by then, we'd have such advanced technology that nothing could go wrong.  
 
Jurassic Park's just a movie, guys. Biotechs and geneticists aren't stupid - they wouldn't clone more than one or two at a time. Plus, we have big guns. As scary as a T-Rex is, a hellfire missile into its head is gonna kill it dead. Dinosaurs would be pretty easy to control - just add kill-collars to them - if they move out of range, if they get loose, trigger the collar/tag to blow them up. Or poison them. If they ever really got out of hand, we've got chemical and biological weapons which would make short work of them. In reality, if the military really wanted to, it could have cleaned up Jurassic Park in no-time. Just carpet bomb + Mustard Gas + Helicopter Gunships + Naval Bombardment = Toasted Dinosaurs.  
 
EDIT: Or what about an A-10 plane you Americans have? Has a Gatling gun on it that fires Depleted Uranium rounds the size of milk-cartons at 2,100 to 4,200 rounds a minute pretty accurately. Such a gun can rip a modern tank apart - a T-Rex would stand no chance in hell. Raptors? Use landmines and clear the area around your base. Raptors can't fly now can they? Is it at night? Use IR or Night-vision to see them. No matter how fast a Raptor is, it's not faster than a bullet fired out of a rifle.  
 
Humanity has the dubious distinction of being the species most able to wipe out other species with ease. Hell, we destroyed the Woolly Mammoth with nothing but a bunch of pointy sticks, co-operation and rocks.  
 
The reason the Jurassic Park guys lost to the dinosaurs is because: 1) the Film would have been boring if the humans won and 2) There was very few of them and they acted like idiots. They had like, what, one security guard? For the entire complex? That's just silly.

Don't see a reason why not. Because A) it would be awesome, and B) I could finally ride dinosaur, like Jesus did in biblical times!

Yes, and they should ship a t-rex to New York, King Kong-style. How could that possibly go wrong?

I don't see why not, real life isn't like the movies.  Even if one of them did go out, it wouldn't take too much to bring it down.  I don't see why it would be any different from an animal escaping from a zoo.. and just how often does that happen?

The only doubt should be whether or not it's ethical.  Personally, I have no problem with it.  If we conserve animals from extinction, why not being some of them back?

" @Chris2KLee: Dinosaurs are a lie! It is god tempting you with the thought of evolution! Don't believe the lies! Jesus road tigers. "

" I think I'd rather have Pokemon than Dinosaurs. I want those badges. "

Yeah as long as they're aren't able to get out and kill people / animals.

Absolutely they should!

Yes, duh. But they would have to find a remote island where they can keep them.

Wether we should or should not, Jurassic Park should not really influence your opinion too much on this. I just re-read the first book, and while it's a great page turner, Michael Crichton really had a lot of problems with his concept of modern science. Something went wrong during his post-doctoral fellowship and he eventually even began to believe in mumbo jumbo like psychics and that all diseases are caused by our minds. Kind of bad if you're a Harvard medical school graduate ... Definitely try to get an informed opinion about the benefits and dangers of genetic research from somebody other than Michael Crichton. He was a good writer though.

" Yes they should "

i think that cloning dinosaurs would turn out so badly... there was a reason why dinosaurs never existed at the same time as humans, and it should be left that way!

We're already creating anti-matter, black holes, and miniature suns on our own planet; I don't see why we shouldn't flip off natural selection as well and bring things back from the dead for our own amusement.

" Sure, what could go wrong? "

" It would be about as stupid as creating a robot that can beat you in jeopardy.  "

" @danimal_furry: Even if it would be possible to clone dinosaurs right now I think you forgot to add the point where the outcome of such a being living in this time could cause catastrophic events. I don't mean dinosaurs eating people and I wouldn't even worry about that, to be honest.. dinosaurs could cause or carry illnesses we can not cure, for example. "

" Cloning and studying dinosaurs is akin to taking King Kong and putting him on stage. It's ethically wrong to exploit an animal in such a way. Not the least of which is that cloning a dinosaur goes against everything that Darwin stood for. "

They better do it quick, Forsyth will be too old to clone soon.
 

Yes and then they should make an amusement park with them!
