Would you like me ro go back in time and ask for their BLM membership card?
Does BLM even issue membership cards?
If and when looters are arrested, do you honestly think that the cops list the suspects' BLM affiliation on the arrest report?
Finally, would you also honestly expect to see the MSM report the fact that a BLM member got arrested for looting? Seriously, keeping in mind that this is the same MSM that gave us the phrase "mostly peaceful protest" whilst buildings burned in the background. No, I think I'd have a better chance of showing proof that Bigfoot took place in looting.
