Here's a complete refutation of your argument: Pretti did not attempt to "de-arrest" anyone at any point. Nobody, not even ICE, DHS, the White House, or the FBI has argued this.
Whoever told you this made it up. You should stop listening to whoever told you that. They are lying to you about this, and everything else they have told you is a lie too.
You are completely out of touch with what the immigration policy of the last democratic government (Biden 2020) was.
It was aggressive, it was inhumane, and immigrants were killed despite a massive effort by people from "the left" to feed and clothe people who were detained in open fields or between two border fences without any care being provided by the US agencies detaining them.
Maybe you are right that nobody who is right-leaning trusts that the US democratic party isn't pro border enforcement and anti immigration, but that's based purely on lies and propaganda.
you can always try the plastic bag + vacuum cleaner trick - take a thin flexible rope, tie it to a small plastic bag, stuff the small plastic bag into the conduit, use a vacuum cleaner at the other end to suck the plastic bag & rope through. You can then use the rope to pull through new cable. If you make the rope twice the length of the conduit, you can keep it in there indefinitely to pull through new cable whenever you want.
No - the obvious play here is for Amazon to undercut the original vendors by 15%, sell at a loss until all of the sales go through Amazon, and then pressure the vendors into cutting their pricing and becoming suppliers subservient to and dependent on Amazon, allowing Amazon to become a middle-man dipping into the revenue stream.
