Several years ago around here there was a rash of church vandalisms. Not just Catholic churches, it seems that the criminals thought that any church would do as a target (what they did to the Jewish synagogue, they should rot in hell for. Swastikas and the like.)
But after that crime wave, the Catholic churches bolted the already-heavy tabernacles down, and a lot of the churches moved the tabernacle of reservation (I don’t think that’s actually the term, but it is where the Blessed Sacrament is reserved) off the main altar to either a chapel or a side altar, to foil the vandals. I guess the thinking was that the miscreants would first go to the centrally located tabernacle, and that by the time they trashed that someone in the rectory would figure out that something was amiss and the cops would be on their way before they figured out where the consecrated hosts were. A lot of churches had locked their doors a long time before the crime wave, but this bunch managed to jimmy their way in.
Crud. I remember when you could walk into a Catholic church, any time of the day or night, and spend time in front of the Blessed Sacrament with whatever weighed on your heart, or just sat there in the company of Our Lord. This bunch of weasels ruined that for everyone.
Going up to the door of a Catholic church and finding it locked is one of the saddest commentaries of our times.
