I won’t take credit for thinking of this. This thought showed up on a social media platform I see regularly.

The shooter who gunned down 12 victims overnight in Thousand Oaks, Calif., is a home-grown, corn-fed domestic terrorist. He walked into a country/western night club and opened fire with a pistol.

A wall across our southern border wouldn’t have kept him out of the country; nor would a travel ban imposed on those coming here from Muslim countries; the shooter wasn’t an Islamic State goon; he didn’t trudge north into this country as part of a “caravan” comprising murders/rapists/sex traffickers.

He was an American citizen. A former Marine. He purchased his murderous weapon legally.

We need to look inward, folks. We are facing threats from within arguably more dire than from outside our borders.
