Yes, these are all good arguments that should be made. Another good argument (implied by your first) is that historically it hasn't been wise to trust the police when they say that a suspect was armed. My point though (and I hope yours) is that giving a long list of people killed by the police under the apparent header of "unarmed" is counterproductive if the people who were killed were not in fact unarmed. Misleading approaches like this (unintentional or not) turn off people who would otherwise support your cause.
