It's not "his" police is it? I mean he can certainly apply pressure, which I presume is what you want him to do, or perhaps show some support, but ultimately it's city's and state's call.
Was reading about their (protestor's) demands today: good luck with that. Like it or not, the reality here is that any, and I mean any, elected president would support Israel the same way Biden is doing (perhaps even more unapologetically so).
The argument, which I happen to not find crazy, is that if you don't want to US to support Israel it would cease to exist. So, these universities are in a bind: they can either take a stance against Israel and appear (which is enough) antisemite, or stand against the protestors, which seems unpopular esp in the liberal media. My money is on that nothing will happen. Kinda "occupy wall street redux."
Regarding Trump vs Biden, I think it goes way deeper than politics or whether you agree with specific policies or not. The whole pardoning for favors alone is already a huge red flag to me. How that shit isn't illegal is beyond me. Then again he asked for votes to be "found" in a recorded phone call, so. 🤷♂️
