-Plainly lying and claiming truth
-Using various faulty logic such as appeal to authority or ad hominem to support false claims.
-The use of a generally correct statement with incorrect context.
(The misinformation here is that while death rate might increase with legal guns, it happens to be that criminals are the ones often being shot during or after a crime. Schools that have been shot up had guns banned from campus, people sick in the head could go into such a school with illegally acquired weapons, these people seek out such places because they know that no one can shoot back. Police only come after the fact and rarely prevent any violent crime.)
Poster2: Misinfo agent detected, when guns are banned criminals continue using them.
