text: Mark Kelly may know a lot about space---but that's it.  He and his wife are clueless when it comes to guns .  No law written on paper can stop these incidents .  Chicago has some of the strictest gun laws in American and ten times as many that died in Las Vegas die there every year .  Criminals won't obey any gun laws, and will always have guns . The only thing gun control laws will do is keep law abiding people from buying guns .  The night of the shooting in Vegas over 150 million American gun owners hurt no one .  So far , from what we can tell , the Vegas shooter would have passed any back ground check that would have been given to him.  People snap---no gun background check can stop that. That's why Kelly and his wife are clueless on the issue .  What has been the latest killing tool of the crazy and terrorists ?  Cars and trucks . Does Kelly and his wife want background checks for them as well ?  Good luck with that . How does he plan to stop millions of motorists ?
