Every country has the right to have secure borders. We have a legal immigration process which works well for those in real need and under persecution status. Otherwise we have work visas and student visas. Just because you want to come to America doesn't mean you get to. At a time when human trafficking, drug smuggling and racketeering is so pervasive we should monitor if those coming into our country are for us or against us. Build the wall. No more free flow of those purposefully avoiding the lawful methods for entry our country has provided.
