Videos clearly show that he has a flashlight at other times because you can see the light on the wall.
It is also very possible for the guy to carry in his pocket or on his body BOTH an injector and a flashlight.
A guy that size could also have a crowbar, a chainsaw, and a German shepherd all at the same time and we wouldn't notice.
The pic I blew-up wasn’t a flashlight. You might have seen him with a light at some time, but it wasn’t in the pic in question.
