We already have border patrol and border security. What is needed is a WALL and mass deportation; without either of those, border security and border patrol is weakened.
If they can build bridges and tunnels through rock, under water, over water, etc., they sure as heck can figure out how to build a darn wall in areas with undesirable terrain.
Quit with the excuses. Build the dang wall and start deporting!
I wouldn't say its necessary.
I reckon more funding for border patrols, strengthen existing laws, give out MASSIVE fines to any company that hires illegal immigrants (Jail time if necessary) , make it impossible for them to open up bank accounts, Pays Bills etc
Right now its just too east for them to go to america, get a job, even go to school etc! cut the Intensive to come and they won't go.
also give the death penalty to any illegal immigrant that commits rape/murder.
The border wall will not stop them from coming in, Unless its covers the entire border, is 30 meters under ground, mate of the harder materials and is frequently patrolled at all times. And even then, they will still most likely get through some how.
However if you stop the reasons why they want to come in the first place, they won't bother.
