Indeed. A very wise military leader agrees with you:
Commander William Adama Commander William Adama:
There's a reason you separate military and the police. One fights the enemies of the state, the other serves and protects the people. When the military becomes both, then the enemies of the state tend to become the people.
I'll also add that the misuse of military vehicles on domestic soil justifies the right of the citizenry to arm themselves with anti-tank weapons to protect themselves.
