Alcohol and smoking with junk food, pollution and lack of healthcare kill ten thousand time more citizens every year.
There is nothing dangerous about mass-shooting, the average mass-shooter is a man who was bullied or suffer from childhood trauma or both, this repetitive accumulation of bad feelings lead them to become suicidal or angry with rage, leading him to commit a disaster.
Politicians will use their political recovery to get relevancy, and people behind the scene, will have an opportunity to apply totalitariasm laws and anti-freedom agendas, and establish a gun control, the removal of weapons from people.
You can't talk about mass shooting, without talking about guns control. Why switzerland, a country where almost everyone is armed, there is no mass shooting every year, no rapes, no home/car jacking. It's about education first.
The NRA always defended weapons in the hands of the civilian, not for justice or freedom sake but for economical profit.
Parents who lost their kids are too emotional to establish a logical conclusion. No children in his right mind will even think about commiting a mass shooting. Your children is the first victim of the tragedy, before you, since you end-up being against gun control.
Mass-shooting are used by the media to portray an atmosphere of fear, more than a billion people on earth live in extreme poverty, near extremely polluted area, hunger, thirst, diseases. Why cares the dozen of death from a bullied kid, who is no longer alive ?
What solutions do you want to bring to this problem ? Removing all guns from the hands of all citizens ? If someone kill someone with a knife in his kitchen, will you take my knife in my kitchen ? If someone kill someone with a car, will you take my car from my parking ?
Establishing metal detector and corporal search near all schools entrance and arming teachers ? The NRA will try to defend it's golden mine and the constitution who made the US what it is today.
