Every news person and politician talks about the wall. It is not the wall that is our problem. It is the law.
We need to change our law that allows anyone who is not from Mexico or Canada to stay while seeking asylum. Change the law and send them home or to a receptive country until the court date for the hearing. Currently, they cross illegally, turn themselves in and disappear. The percentage that appear for the court date is small. Changing the law would solve most problems.
