You are woefully ignorant of police. An MRAP does not make the average cop think he is in danger. It makes the average copy think he is safer because other cops are here and we have a whole lot of intimidation with us. MRAPs are not used for a lone cop on patrol, its used for groups of cops in special situations.
The steady rise of no-knock warrants over often petty offenses would suggest otherwise.
Selection against intelligence, a bogus claim. The two guys I went to high school with who became cops were taking all the college prep math and science classes and doing quite well, trig, pre-calc, chem, physics, etc.
Courts have backed police departments for not hiring police officers that scored too well on a test. I'm not saying that it's a universal problem, but it certainly doesn't help.
Speaking of groups of cops. One of the most effective ways to reduce their fear is to not send them out alone. When a partner is present a cop is far more likely to use a less-than-lethal weapon like a taser or baton than his gun.
That is probably true. Equipping both with a body cam would probably also greatly reduce the plausibility of 'malfunctions' causing footage being lost.
