First off, sorry I'm responding this late, I never use this site. Second off, I'm not assuming you're a murderer, but, others have certainly used guns to kill other people, including the police. Masks are an easy way, not to protect yourself, but to protect others, in that, protecting oneself. I couldn't even choke the air out of someone with a mask if I tried, because they are meant to breathe through. I'm not saying ban guns, but there should be much stricter regulations. This does not apply to masks, as there are no cases of masks killing someone, but there are of cases of not wearing a mask doing exactly that.
