Me too. And the people in charge of the apartment building testified that there have been multiple other cases of people in that apartment building mistaking another apartment for their own. It happens.
I didn’t follow all the trial testimony; was it clear whether Guyger would have been able to see Jean’s race? Racism may have played a part in that Guyger assumed intruders wouldn’t be white, and she had racist views, which may have made her more likely to shoot an unidentified intruder, but could she see Jean well enough to know he was black?
