I'm not sure diplomacy works when someone is actively shooting at you or other people.
If people are rioting (actually rioting, not protesting) then I honestly don't care how the presence of a MRAP makes them feel. It's the police's job to stop the riot and they need tools to do that.

I'm glad you're not the majority. Because the world would be pretty shitty if all the police responded to was physical assaults and above.
