That's the time frame you think they are referencing.
Seriously -- you don't actually know if it happened or not. They may well have embellished ... hell, they could actually be lying.
But if you think there aren't folks at these rallies who aren't fully capable of acting as these guys allege, you're fooling yourself.
Again, why don't YOU provide YOUR evidence?
Here you are, busy making wild allegations without as much as ONE SHRED of evidence to back it up, yet you keep spewing off at the mouth anyways, despite testimonies to the contrary by Freepers who were actually there, despite video proof, despite the fect that the huge number of MSM cameras still never produced ONE IOTA of evidence to back up any racist attack..and STILL you wouldn't shut up.
