I would not object that you might be less sympathetic to some criminals than others but as far as I can tell criminal courts don't judge one's character.

Even if you claim that you can judge one's character by a mistake He/She did in the past, news organizations are not always accurate or might not portray the picture factually.

Maybe it's better if you ask Mark for past convictions and give him a chance to explain so you can judge his character in an informed way.
