That's a mighty broad brush you are painting with there.
Part of why the militarization of the police is so scary is because most of that equipment is given under a "use it or lose it" clause. So they have to use their tanks, otherwise the federal government will take them back.
So, they have to find "reasons" to use them even if they aren't necessary. Maybe one day in the far future they might be useful, but in the meantime they're basically toys.
