Honestly, if there are legit X-rays and MRI's that back up a supposed injury, you can fuck off about your post. Those X-rays and MRI's haven't been produced, but since you are obviously not a Radiologist or Orthopedist, you don't have much room to stand on how the supposedly injured should react. Just wait til the evidence is produced.
A man beaten to the point of near unconsciousness and with fractured skull parts etc. would clearly not be standing around shooting the breeze with a fellow cop
