Yes . . . not only culpable for murder, but culpable of “murder for money.”
I argue that these politicians have a lot in common with a mafiosi hit man, as they accept money and campaign contributions from gun lobbies (like the NRA) and gun manufacturers, when they know in advance that innocent people (including children) will die because of this.
As long as they get the money, they push to restrict legislation on gun control.
Even so, I must disclose (in the spirit of honesty) that I do own two guns for my hurricane and disaster supplies . . . but I submit that a bolt action hunting rifle with 4 total rounds, and a single-shot .22 is different than an AR-15 assault rifle.
