there is plenty of room to blame both the legislative and executive branches for allowing and using (respectively) our government to torture children. both have the constitutional authority to remedy the situation without any need for cooperation from the other branch.
I understand how torture can be used in this context, but I roll my eyes heavily when considering people who are truly tortured around the globe and through history. I tend to take those comments as hyperbole.
I will agree they both have the authority, but as has been proven with Trump's rollback of a lot of Obama era programs, the executive branches decisions lose permanence with the change in power. This makes it very difficult for any private or public organizations trying to assist immigrants and the immigration process to make long term plans or understand the steps to take to keep these situations from being so haphazardly handled. A legislative change would most definitely have a time frame for application allowing for proper organization and planning. This may also encourage those seeking to immigrate the patience to wait their turn knowing that an understandable process is in place.
By leaning on the executive branch in this way you run the risk of endorsing chaos with a change in power.
Trying to figure out which part of the constiution is being infringed upon.
I would say the separation of powers. The executive branch has waaaaayyyyyy too much authority. That didn't start with Trump, but it is blatant in every criticism of him. I realize that congress needs to be at least a little adversarial so only the important laws get passed, but its current complete disfunction makes it more and more ok to the public for executive overreach. The more we prefer that Trump just steps in and "fixes it" the easier it will be in the future to completely ignore congress and rely on one man to make all of the right choices. The checks and balance system in our government is broken.
It didn't start with Trump? Ya Think?
We're currently dealing with a meaningless nuclear non-treaty that the previous guy paid $5.2 Billion to a terrorist state to obtain without any consent from Congress. That's just one example.
It didn't start with Obama either, but the obstinate actions of congress towards the end of his tenure led him to make irrational choices (IMHO) setting precedent for overreaching executive action. There were better ways for the republican controlled congress to handle Obama that they refused to do. A LOT of people are to blame, but this is the most proven case of "slippery slope policies" that I have seen in my time following American politics.
