Gun control provokes intense whataboutism: "Thoughts and Prayers" "What about mental health!" "What about MS-13 and immigration?" "What about drugs?" What about everything except considering restrictions on ownership, licensing, etc.
A terrorist can kill a few dozen people once every few years, and suddenly we need a massive surveillance state, hundreds of billions spent on military and intelligence, "extreme vetting" of immigrants, travel bans, etc. But domestic mass shootings can happen on a weekly basis and it's business as usual.
