The head medical examiner is, as Prof. James F. Tracy stated, "either under coercion or an imposter."
More speculation based on body language: is that really all we have to go on?
I suppose the Professor's analysis might be accurate. Then again, as far as the strange body language goes, there's also the prospect that the guy was just nervous in the national spotlight ...and is now being berated and accused of highly offensive things because of it.
In any case, whether he was under coercion during the interview or he's just another bad actor (or whatever else), he might not have done the playwrights any favors by confirming that the "long weapon" (I.E. the assault rifle that was reportedly left in the trunk) had been used on all the victims he personally examined.
Needless and probably painful (for the families) innuendo by CT twits with too much time on their hands. MisterBeale, like 9/11 HandJob and Paulitician seem to have little connection to reality and give all CTs a bad name (not that most CTs need any help).
