Gun Laws to be Revisited in Wake of Newtown Connecticut Shooting

So will now be the time that leaders have the courage to participate in meaningful discussion about gun laws? Not log ago, Arizona Congresswoman Gabrielle Giffords was gunned down in Tucson in 2011. House Minority Leader Nancy Pelosi (@NancyPelosi) tweeted, "No words can console the parents of the children murdered at Sandy Hook. We share our prayers and our grief over these horrifying events." Comments like those made by Nancy Pelosi are echoed time and time again, but still the violence never seems to stop. This time in Connecticut it was innocent children, in their elementary school, 20 victims between the ages of 5 and 10 years old now dead.
So a call for gun limits are now echoing again, but will the call fall on deaf ears? Other such incidents, the Columbine High School shooting in 1999 and just recently in Aurora, Colorado in 2012, are just added horrific and heartbreaking incidents that affect everyone. Yesterday it was an Oregon mall shooting. This time, parents all across the country are affected, wondering if their children are safe at their school. The TV reporters are passing the word that the children are safe in schools, but how can the news media make such false accusations now, especially since this happened in such a small community  in an elementary school just this evening in a small town of just 27,000 people.
Do all schools, no matter where they are located, have metal detectors? The fear now is that there may be copy-cat killers wanting to carry out a similar crime.
How do you limit guns when you have the second amendment to the Constitution giving the people the right to keep and bear arms? You have a right to possess a firearm, but will they limit the sales of them or should they?
In some states, you don't even have to give your name. All you have to do in the state of Texas for example, is to first decide what type of gun you want to purchase. Shotguns and Rifles are easier to purchase than handguns. Then you have to pass an FBI NICS background check, which is required by law. But you are allowed to possess a firearm on the premises where you live after 5 years have elapsed since your prison or parole term has ended. They use whichever term is later.
There is no waiting period in Texas when you buy the gun from the dealer. If you passed the FBI NICS background check and receive your CHL (if required), you can walk out of the store threat same day with your gun.
After shootings similar to the school shooting, the purchase of hand guns, especially since the news reporters have reported which types of guns used, become popular and sales rise dramatically. It is my opinion that gun control laws must change in the State of Texas, and sales should be limited. The Second Amendment to the Constitution still guarantees the right to bear arms, but it should not give users of firearms the right to target innocent victims for a kill. Presently, there is no way to stop a cold calculated killer from using his guns illegally  so essentially we are giving purchasers of handguns their right to do what they please, at a consequence which always seems too late to make a difference. .
