Nope, just the opposit. MOM showed how difficult it would be to see it. Did you not see the coat GZ was wearing?
I am pretty sure you are wrong. I can’t say 100% because I like to leave room for error...
Now I have to find it before I go to bed because it is going to bug me.
Here’s some photos of Z in the police station. Clearly his jacket is long enough (6” to 8”) to conceal a pistol in a inner waist belt holster such as his. And seeing as how it was raining, I’m guessing the jacket was zipped up at the time of the attack. But not sure. Although mine is still well covered by an unzipped jacket.
