They should focus on enforcing internal immigration laws (arrest and deport) and remove cities sanctuary laws. Take away all benefits for illegals and reverse the "anchor baby" decision.
Unless they do that, they can put 20,000 border patrol agents on the borders and it will still be like trying to plug a leak in a dam with your finger.
(IYO)How should we go about finding the illegals that are here already?
Agreed. In addition, I just saw a report on FNC that showed kids getting out of school and getting on a bus and a trolley to go home to Mexico. What is up w this??? This is the 1st time of heard of it happening. So, in addition to paying for education, healthcare, etc., etc. for illegals, we're now paying for education for Mexican children???? This is ridiculous unless their parents or the Mexican government is contributing $1.2k per child (I think that's what the said the CA education costs are).
