99% Of the problem is Mexico. Shut THAT down, and the rest of it becomes manageable.
99% of the problem is certainly cause by illegals from Third World countries...Mexico being the biggest (but not the *only*) offender.
*ALL* illegals must be expelled..regardless of race,gender,age,country of citizenship,etc.Illegal Canadians,Brits,Irishmen,Italians,Russians,Nigerians,Kenyans,Brazilians,Aussies and Mexicans *MUST* go...along with all the rest.
