They tore down the library, where most of the kids were killed.
I believe the McDonalds, where the San Yesidro massacre took place was torn down just after the killings, It seemed to be the catalyst on public mass shootings.
This killing also inspired the anti-gunners to go after rifles, something they said they would never do.
Remember this lie?
“WE don’t want to take away your guns. We ONLY want to control handguns! Long guns will not be affected!”
