I think that it is a good idea because many of the Mexicans are sneaking in drugs into the United states and many more are still doing it. I think the building the giant wall between the UK and Mexico is a very good idea.
I also think its a good idea because Mexico is dangerous and many gun fight happen near the UK boarder, were they try to smuggle drugs in the UK. It also helps the police officers to not get hurt if the Mexicans have guns, also helps the Police officers not going back a fourth to the UK boarder.
I really do think that the wall is great and should stay like that forever.
