The Active shooter on Las Vegas strip thread (http://www.mmo-champion.com/threads/...-strip/page174) has gone on to be a thread with the same discussions and posters as the existing megathread on gun control (http://www.mmo-champion.com/threads/...Control-Thread).
There's really no need to have an extended discussion running in two threads and at this point the Las Vegas shooting is no longer an active shooter situation. If the knife/sword/switchblade discussion merits a thread, then let it stand on its own as a clearly labeled discussion of them.
