Dude did come real close to running over an officer, and high speed pursuits are dangerous.
That said, beating people that deserve it but legally should not beaten is also a no-no.
Call it even, or toss both in the clink?
Goes back to one of the themes I'm repetitive on here over "Institutional Evil" as an emergent property of a system, polity, or organization.
People are reluctant to face the problem, or fail to acknowledge it, because there's no twirling mustache villain, megalomaniac etc. who is deliberately plotting or engaging in evil. 99% of the time the police in this instance did not, and never have woken up thinking: "
Gee. Hope I can really beat the *expletive deleted*it out of someone today!"
However, groupthink, peer pressure, adrenaline, anger, the erosive effects of dealing with the dregs of society day in and out all take it's toll. And the fact the victim of said brutality is more often than not of the criminal class, or at least on it's fringes doesn't help either.
Discounted to a degree, because no one is willing to replicate the experiments and get controls, such as Milgram and the Stanford Prison experiment, but there's a hint that there's an Auschwitz tower guard in all of us, given enough time, and the right leverage.
