Almost certainly a FF. Noone will know how he was put up to it or conditioned to do it for some time. That said those proposing that they are crisis actors playing the victims are idiots. To pull off an attack hoax you have to be able yo control your environment. A Wal Mart parking lot on a Saturday morning is one of the least controllable/unpredictable locations on the planet and would be the last place chosen for one of these operations.
This plays perfectly into their narrative. Antifa communists funded by the cult were already headed to El Paso. Upon arrival the MSM will be pushing that a white male slaughtered invading hispanics that he was warned about on hatechan. In the minds of the simple any and all actions taken by POTUS against Antifa in El Paso will associate him w a mass murderer and at the same time attempts to justify Antifas past and future violence against Trump supporters.
