I've witnessed IED's, VBIED's (car bombs), rocket impacts (one less than 40 feet from me), and mortar impacts while at war.
This is absolutely not what they are claiming. This is a bold face lie.
A lot of chatter from Vance and others about the closure of I5 even being necessary. Turns out, it was necessary, with CHP cruiser damaged by shrapnel from shell that detonated early. Imagine that happening on the freeway full of regular Saturday traffic.
