If ever there was an issue where the GOP is on the wrong side of history it is this. (Yes, I know there are other issues as well with this current GOP). This strikes to the core of who we are as a people. Do we truly value life?? GOP are you just pro-life in the womb? If you say you are pro-life, then it is time to step up and agree to reasonable new gun laws. It is time to adequately fund mental health programs. A whole new look of the 2nd amendment must be taken- does the 2nd amendment allows for and was it the intention of the constitution's writers to allow citizens to own weapons of 'mass destruction'? There weren't AK47s back then, but there were other weapons that could cause multiple deaths quickly. Unfortunately, the toothpaste is all out of the tube and you can't put it back in without splitting the tube wide open. There are so many of these types of guns available for deranged people to use - to ban them will not result in 100% security from their use. A ban will be as effective as prohibition and will result in episodes similar to Waco, Ruby Ridge, and OKC- as fringe far right military type groups will resist a ban on such weapons. With that said, I say - ban the d#$m guns. They have no useful purpose for the average person.
The other thing the GOP could support is a massive increase of revenue for mental health programs to identify and help the mentally ill persons who may initiate such a shooting. It is true, that if a gun isn't available the mentally ill person may use other means. However, the availability of guns makes it easier for the ill to or the criminal mind to commit the crime. It is harder to fall into temptation when the sick mind is speaking when the means aren't available.
Note: the Dems support all of the above. They are pro-life.
