Three men are in custody, charged in three separate cases of domestic extremism last week.

Two were deadly shootings — one at a synagogue in Pittsburgh, Pa., the other at a grocery store in Louisville, Ky. — and the third involved explosives sent through the mail from Florida.

The suspects fit a pattern well-established in recent years: troubled, American-born men who appeared to be acting alone and driven by hate.
