I do not think that cops travel by city bus.

This could be political cover for a policy not to transport anarchists into battle. But I doubt that a bus driver wants to enforce this rule against a gang of psycho Antifa members.

I believe this refers to bussing cops between a staging area, and a deployment area. That probably happens by bus. You don’t want them driving their POVs or squad cars into the riot zone, parking them, trying to assemble, then leaving the vehicles behind.
