When I went to school from 1946-1958, people had guns in the home, they hunted whatever. People carried pocket knives in their pocket in school whenever. No one thought of shooting in school or shooting another person.
We had movies back then where the bad guy got shot; comic books with good versus evil, still no shooting in the schools.
Now we have movies, TV shows and video games that show multiple shootings and killing of people, as well as explicit blood and guts.
That is the difference from then until now. All Hollywood says is no.
What do you think? Let's register and vote it will change. All the laws can be made, but if a person wants to kill, they will still have guns, knives or access to get what they want.
