Point 1..
I think you could ask the same thing to Obama but the reality is that it takes time for these problems to make it up the chain of command. Then once it gets there, they have to come up with solutions that work within the legal framework and get money for the solution. If the solution within the legal framework still has holes, it's up to congress to write laws that address that. Bush, Obama and Trump all asked Congress to get off their ass on this topic but they have been terrible regardless of which party is in charge. That's why I don't think you can blame Obama or Trump for the problem. Things like this take time to fix.

Point 2.
Verifying the relationship between the minors and the adult accompanying the minor is pretty important because of the potential dangers the adults that aren't the parents pose to the child. This article came out this morning...
http://www.dailymail.co.uk/news/article-5946471/DOJ-adults-separated-kids-border-murderers-child-abusers-kidnappers.html?ito=social-twitter_dailymailus
According the the US government, over the past 5 years 46 of the 103 small kids separated from their families were deemed unfit to be returned to the adult they traveled here with. The natural response to this question is why?
-In multiple cases the Adult was not their parent
-One case an adult was accused of abusing the child in Mexico.
-One has a contagious disease.
-Multiple adults had been charged with murder and are in jail.
-Multiple adults had charged with kidnapping in Mexico.
So the batting average on these cases seem to be pretty high all things considered. I wish we knew the exact number of cases of each thing, but I am in favor of separating children from child abusers, rapists and murderers. I can assure you this is a better batting average than CPS.
The good news for those 46 kids is that even if they do not find a blood relative to take them in, they are guaranteed asylum under our current rules. While foster care isn't an ideal situation, i'm sure that there are plenty of people out there that will be opening their arms and adopting them.

Point 3.
I haven't committed genocide and I'm not going to take blame for any just because I might share the same skin pigment as someone who did. If you use that criteria, no one is free from the genocide blame game. Ever skin pigment has committed genocide on a mass scale. Genocide is the #1 excuse people use to come here. After white supremacists the cause of ethnic cleansing in South/Central America? What about Africa? Asia? Middle east? Ethnic groups have been murdering each other for thousands of years all over the world. It's not something exclusive to this continent. If anything, this is one of the few nations on earth that has grown above that kind of crap.
You are using the same logic white supremacists use to claim superiority. Since they can't claim whites are superior based on IQ (which they aren't), they now default to technological advances as their go to. However, that's a flawed argument. Just because some white dude 100 years ago invented something, doesn't mean a white dude working at Walmart gets to take credit for it.
Circling back.. You might think genocide is going to come to the USA but I don't see anything like that happening based on 46/103 small kids being separated from monsters that had them in their clutches. Are you willing to sacrifice those 46 kids so that the 57 other kids don't have to be separated? I am not.
