1. Police on Police

what happens when two police using the same type of radar clock each other going in the opposite directions? Can they read each others speed?

Yep, they can read each other's speed no problem.
If you want to know WHY they don't interfere with each other, see my explanation in this thread:

3. But if one gives the other a ticket, they're sure to get out of it by arguing to the judge that their radar interfered with the ticketing LEO's radar...

4. So in order to make that work, you'd have to fire YOUR radar backward, bounce it off something moving behind you, and have THAT signal read out on the other officer's gun in order to produce a doppler shift. Right? Of course, that's about as likely as the LAPD not beating a black suspect....

Not even that would work.
The doppler-shifted "bounced signal" would be in reference to the [exact] transmit freq of your radar unit. The officer's radar unit is likely to be a number of MHz off of yours, so although it might receive the signal from your radar unit, it would be completely outside the bandpass for a normal speed reading (a number of Hz or kHz off of the transmit freq), so the signal would be completely ignored by the officer's radar.

Gotcha. So it'll only be a few months before RMR offers a product along these lines...
