Are you suggesting that a CCW holder would have stood a chance against the shooter, with basically automatic rifles, who had cameras rigged in the halls so he could wall bang approaching people, if he so happened to rambo into the hotel room, without breaching charges, and got into a shootout in the room?
I assume you know the answer but lets be redundant.
Our country was founded on a massive rebellion from a country seen as tyrannical. It lead to a war, you've probably heard about it. Written into our wholesome Constitution is the provision that would limit the government from restricting our access to firearms, which were and still are the best personal weapon for defense. This is necessary in the event that the United States does a heel turn and the citizens need to protect themselves. I could draw parallels to what is happening in Spain. If Texas wanted to seceded from the union, which they commonly threaten, the federal government will have a tougher time preventing that.
I would never feel the need to carry a pistol on me at all times. That's a bit paranoid. But you damn well bet I want a 12 gauge sawed off by my night stand so when I hear my dog barking I know full well I'm gonna protect my shit. I'm too small to rely on my using a club or bat better than the other guy.
