The next most prominent issue is crime

This problem cannot be solved with city planning.
College campuses have long been designed with combatting political gatherings in mind, that is to say, they do not have wide open squares for which large groups of people can organize large protests. Their spaces are made narrow and intimate, you are always in some corner of a campus but never a prominent center.
However as you may have noticed, this is completely ineffective because controlling humans through such design is just generally not that effective.

like trying to save a sinking ship with a pail of water. It removes water yes, but it's not going to save the ship.

Only law and order can stop crime, and only culture can prevent crime from ever emerging to begin with.
The police must do their duty properly without complacency or corruption, and parents and educators must do their duty also.
