It says there's clear and convincing evidence that hcq may be beneficial.

That sounds fishy to me.

If the evidence is clear and covincing, it should say hcq IS beneficial, not that it may be beneficial.

"We have clear and covincing evidence that the defendant may have killed the victim."

In what world is half the jury not thinking now that the state's case is weak?
