The is a simple way to end a repeat of these mass murders.
If the perp survives, hold a trial within a week, while it’s all fresh in everyone’s mind, even the bleeding heart liberals.
If convicted, start building the gallows outside the perps place of confinement, and make sure the murderer can watch the construction.
Once the gallows is tested and working, dispatch the convicted criminal.
The bleeding hearts can assemble at the gallows to weep and wail for their soon to depart convict. Justice, the way to make wannabe criminals take notice.
There’s no way to end the nuts from doing terrible things, but they only get one chance with this justice, yet libs can put on there show of how much they care for every human too.
