While I'm an evangelical low-church Protestant I have noticed coverage at GetReligion of a spate of anti-Catholic arsons and vandalism as noted at GetReligion in the last year.
That is background that Clemente Lisi touches on in recent coverage of the confirmation of unmarked graves in cemeteries at Catholic-run residential schools in Canada.
Lisi highlights a lack of coverage as to who is suspected of perpetrating the vandalism and arson. If there are suspects that has not come up.
