I think if Trump hadn't been fought tooth and nail, he'd have done mass deportations his first term
remember, Democrats/liberals did everything they could to stop Trump and deportations, they fought HARD (as they are today) to keep millions and millions here legally
just look in 100 days how they've tried to stop deportations

and his first term

but, I've always said what happens on a President's watch is his to own. The El Salvador citizen that killed your neighbors? it was because of a unsecured border. Trump is trying hard to fix that now, where GW, Obama, even Trump 1.0 and of course Biden was horrible .... but that did happen in Trump years.
I mean I don't know what you want from him - if he deports all the illegals then of course no illegals can commit crimes like the one you pointed to. That's great - but how's he going to do it? with all the lawsuits and Democrats fighting him daily ... do you support him being a King and just doing it ?
