Red John can't be Bob Kirkland...I mean he killed a man in a hospital!
Red John doesn't make the "minor" kills.He kills when he wants to get
Jane's attention and always leaves a smiley face at the crime scene.The
exception would be in the season 2's finale when he shots 3 teenagers
and cuts the girl's neck.But he did that just because there wasn't
enough time to kill them in his notorious style. Sorry for my
English,it's not my native language.
