In addition to facilitating human and drug trafficking, their sewage finds its way to San Diego beaches! Last year they were 2nd only to Syria in terms of fatalities...
A very small handful of illegal immigrants are cartel members. However, it's less common than many people believe it to be. While there certainly is a lot of violence in Mexico, most of the illegal immigrants are actually attempting to flee the violence that is occurring in their home country. The sewage problem definitely sounds quite disgusting indeed from some photographs I've found online, but the dumping of raw sewage into the Tijuana River would occur even if no one was crossing the border.
Our southern neighbour had more murders than Iraq and Afghanistan! They should quit blaming everything on us and take responsibility for their own corruption and incompetence. They must know where the cartels are, they could be using drones to take out their safehouses.
I don't think they do try to blame us. Unfortunately, the police in Mexico usually don't do anything about the cartel killings because in many (if not most) parts of Mexico, the cops are getting paid off..... so nothing changes. However, if they did manage to stop or reduce the violence from the cartels, there actually likely would be far fewer illegal immigrants from Mexico. Not so sure I agree with using drones though. Drones tend to create a lot of civilian casualties.
The ONLY reason liberals want the border open is because it means more votes. They don't care that the illegals undermine our politics, access welfare, access healthcare, and steal social security numbers.
As a liberal, I don't want the border wide open and agree with you that illegal immigration is a problem. I'm just not so sure that we need to build a wall or take other equally aggressive measures of keeping illegal immigrants out.
Luckily, the illegals rarely vote. This is a misconception that has been propagated in recent times, but there have only been a handful of cases of illegal immigrants voting. They do occasionally access welfare, but this is also not all that common due to the lack of documentation.
The stealing of social security numbers by illegal immigrants is shockingly common though, and this is a problem that needs to be cracked down on. This is perhaps the most serious issue that is created by illegal immigration. I feel that laws should be in place to ensure that employers verify that the social security numbers they're receiving are legitimate.
