Most people don’t know this inconvenient truth and the lying MSM won’t tell it: an European law compel any member country to host and process any migrant AS SOON AS he sets foot into the country. So if guards catch a migrant who has just crossed the double fence and throw him back to the African side, they commit a felony and there are plenty of NGOs which will see to make them pay for it.
The “host and process” steps take years to complete and in reality, the border countries (Italy being the worst offender) just release the migrant who is then free to roam Europe.
This is why hordes of migrants “storming the fences” is a daily routine.
Another problem is that the countries where immigrants land are also the ones with the least amount of money to process them. Spain and Italy have plenty of homegrown problems. I don't know what the welfare situation is like in Italy but welfare as we know it doesn't exist in Spain. If they don't take care of their own citizens they sure as heck aren't going to take care of illegal invaders, no matter what the EU says. Even though I live only 20 kilometers from Motril, one of their main processing centers, the only Africans I ever see are the dozen or so regulars working at selling counterfeit clothing and handbags, probably the largest employer of illegals in Spain. The rest head for the border as soon as assistance from NGOs run out. They know there is nothing for them here.
