Everyone who wants any anti-gun “law” is promoting mass murder.
Any politician who proposes any anti-gun “law” is befriending mass murderers.
Any cop who enforces any anti-gun “law” is collaborating with mass murderers.
That is the simple fact of the matter, no matter how you feel about it.
Stating this fact during or immediately after a mass murder occurs, knowing what the anti-gun bigots will already be promoting, may not seem “in good taste” to those anti-gun bigots who want to preach without contradiction (or to the wishy-washy folks who enable them).
Well, neither is mass murder or encouraging it.
