it's pretty obvious how the cops should have handled it but since the cop in this thread doesn't have the intelligence to figure it out (we can't blame him, PDs have literally sued for their right to refuse to hire intelligent cops. you have to be mentally disabled to a degree to get the job.) i will explain it.
tail the truck with a police helicopter. let it drive out of populated areas until they either bail or it's out of gas. arrest them or neutralize them if they force you to. this is how several police departments already handle chases because they've recognized that things are far far far far worse for literally everyone involved if they confront fleeing suspects in public.
if they kill the hostage that's sad, but guess what, the cops murdered the hostage anyway and also killed another bystander and endangered dozens of others by using them as meat shields.
every single cop who responded to this call should be in prison.
