@ RealityCheck, good read, sorry to hear about your cousin.
Setting the race topic aside, I believe these new "flash mobs" are mini public displays of power.
It shows we as a people no matter how you try to rule us, will always win. Your riot shields will crumble.
I totally support congregations like this as long as bystanders don't get hurt in the process.
Take my tax dollars to fix the town, money well spent to prove how powerful we are.
