If we are both in public and you decide to use your fully licensed and 2A permissible gun to start shooting in random directions then you will be liable for the consequences. Declaring that just by going out in public everyone else has decided to assume the risk that you are a dangerous asshole is not going to be acceptable and you will face legal consequences for your negligent behavior. Just because the weapon is a virus you may carry rather than a gun will not change your negligence.
