So are you counting his alleged intentions to violate the law as actual violations? So far even Biden has managed to sell the American people on that notion, though not for lack of trying.
++ As I said, I don't know if his attempts to violate the law were overturned, moot point now. So for example, Trump moved to decline asylum people fleeing drug gang violence, a violation of the Refugee Act. I don't know if he ever did so before he was stopped by the courts or if it came to that.
Both extreme liberals and extreme conservatives show a marked tendency to enshrine laws as religious precepts, as long as they're laws a given group agrees with. If not, they're "bad laws." The simple truth is that all laws exist in a constant state of re-negotiation. I've seen allegations that Trump attempted to modify aspects of immigration law for his political ends, just as Biden is doing now. Modifying, however, is not breaking; modifying is a process of re-negotiation that takes place through legal re-interpretation.
++ As to "modification" of laws, you have to distinguish between what is within a president's discretion in immigration, e.g., Carter's allowing Mariel Cubans to come to the US en masse, or ICE under Trump allowing into the US people who meet a minimal standard for asylum, from what is mandatory, e.g., allowing someone to apply for asylum "irrespective of status," i.e., whether they are here on a visa, at a port of entry, here illegally, etc.
I looked up the usual online source for the United Nations Convention Against Torture, and found this definition of torture:
"For the purpose of this Convention, the term "torture" means any act by which severe
pain or
suffering, whether physical or mental, is intentionally inflicted on a person for such purposes as obtaining from him, or a third person, information or a
confession, punishing him for an act he or a third person has committed or is suspected of having committed, or
intimidating or
coercing him or a third person, or for any reason based on discrimination of any kind, when such pain or suffering is inflicted by or at the instigation of or with the consent or acquiescence of a
public official or other person acting in an official capacity. It does not include pain or suffering arising only from, inherent in, or incidental to, lawful sanctions."
Note first that the convention focuses on torture for the purpose of obtaining information or confessions, punishing the subject for crimes, or intimidation. Note second the final sentence:
"It does not include pain or suffering arising only from, inherent in, or incidental to, lawful sanctions."
++ Sorry, I didn't explain clearly. I didn't bring up the Convention Against Torture to make the case against "kids in cages." But that ratified treaty includes what is called a "non-refoulement" provision, the prohibition against returning someone to a country where they might be tortured. It is similar somewhat to the non-refoulement prohibition in the Protocol Relating to the Status of Refugees.
If you're holding up the Convention as a model of probity, then you need to make clear what form of extra-legal torture you think Trump committed. not just, say, spout the usual "kids in cages" routine. Especially not now that Biden has done his own caging.
