Specifically because I live in a hot climate, I’m always fighting the feeling of being suspicious of anybody I pass in the streets with a hoodie pulled up. I feel guilty because of racial profiling associated with hoodies, but gotta protect myself and my family, especially because in many cases the perpetrators of assault and murder seen in media is somebody with a hood and/or mask on.
Just to comment on a specific part of your question, there’s probably some selection bias to seeing more criminals in the media masked/with their hood up.
Particularly in the case of notices requesting that someone be IDed, if their face is clearly visible and in good resolution, they may not need to publicize it to have the person identified (pretty sure they can search by face in correctional/dmv databases) vs if part of their face is obscured or the only visible marker of identity is something like a tattoo or scar, they might need to publicize it more to find someone who will be able to identify the person based on that limited info.
