Does this mean Luigi’s propaganda of the deed was successful?
Luigi's action was successful - and a lot of that success had to do with the fact that Luigi was not seen by the public as an overt political actor... merely somebody screwed over by Big Healthcare Inc.
Overt attempts to "rinse and repeat" this as a PotD "process" is going to backfire and come crashing down to earth hard.
Besides... reading those messages engraved into the casings I have to wonder if the shooter hadn't gotten it into their head to do a "false flag" op all by their lonesome - they are pretty damn cringy.
