>>>It would be a hell of thing if people could be sent to prison or death just because a screaming mob demanded it.<<<
Scott Peterson comes to mind. He was sentenced to death on circumstantial evidence with the prosecutors actively suppressing exculpatory evidence and testimony so I fully expect he’ll walk on appeal.
Circumstantial evidence is often better than eyewitness testimony. Humans are weird that way.
But a prosecutor sitting on exculpatory evidence should be criminal.
