"They're" not sending anyone. Do you seriously think the Latin American governments are sending people to cross the USA border? No, people are sending themselves to escape violence and poverty, I'm pretty sure you'd risk crossing too if you had to go through some of the shit in these Latin American countries.
You clearly don't follow politics very closely. Here's a liberal media outlet source if you had any doubts.

The mexican govt. produced cartoon style pamphlets w/ advice on crossing the US border illegally. Hope it helps. Most children who show up at the US border aren't accompanied by a relative. If you'd send your kid on such a journey alone you're already an unfit parent. Here's another liberal media outlet letting you know what happens to those kids.

80% of those girls are raped as they try to cross into the US.
It's not just the govt. sending people across the border. It's also the cartels.

So let's recap.
We have shit parents sending their girls predominantly alone and w/o a family member to cross the US border w/o an adult or family member where there's an 80% chance they'll be raped. We have drug cartels digging tunnels and shoving tons of ballons up peoples ass to smuggle shit like heroin in and we have the Mexican govt. producing comics w/ tips on how to illegally cross the US border safely.

This huge spike happened on Obama's watch.
Many of these shit parents sending their kids alone on a journey to be raped have cars and a place to live in the US.
Oh look Hillary Clinton thinks unaccompanied minors trying to cross the US border should be sent back

Why don't you get back to me when you learn to read and follow current events. If you struggle w/ reading it's ok the mexican govt. has produced a great comic for you w/ pictures and everything.
"Rape can be perpetrated by anyone along the way, including guides, fellow migrants, bandits or government officials"
