Durakken was somebody in the old CoH forums who was somewhat infamous for paying zero attention to the shows he was watching and then calling out logical inconsistencies that weren't. For example a group of us would live message while watching Stargate Universe. One episode the group was running for a stargate when one of the ships that was strafing them blew a big piece out of the ring. The scientist said that with a piece missing the gate couldn't dial out. Durakken immediately popped up with the comment "This show is so stupid. If a piece was missing from the gate how did they dial in in the first place. And why did nobody notice it." And he would do that sort of thing all the time.
And I still say that is concrete, not drywall. But yes, shatter could have handled that in seconds.
