wall off the mexican border? they say the terrorists can just walk over here if we don't! immigrants can just run through the brush and be our problem. a wall will fix everything, right? well, can't the terrorists walk south also through the bitter woods of montana or something where we don't watch? heaven forbid they just drive their boat off a yacht straight into a harbor pull ashore somewhere. i don't see the need for a wall as it can keep people in as much as out. yet it seems to be the common thought that it will fix everything, or at least help. thoughts?
