I'm not opposed to border security. I just don't think that building a wall would be a cost effective means of achieving that goal. Plus there would be some negative environmental impacts.

It depends on the location and if it's combined with other things. An unmonitored wall would add little by itself.

In some places there already exist walls and they do help.
