Lights off happens by time due to outrages ( look heavy rains / snow ), but even if, light inside vatican was not off, it was clearly visible lights from the windows, plus the police didn't go in the church but in one of the lateral offices, Shooting, i had the live video going, didn't hear, but even if, that's Rome my friend, Roma and Napoli ( Southern Italy generally ) has daily shootings, robbery, mafia and derivates, drug deals, and so on, it's really a "Dirty' city, you wouldn't want to go around dark zones the night, trust me. Calling for backup is a matter of seconds, the Vatican is inside Rome, so the police is always around, plus, they have 24/24 patrols outside that have direct contact with Italian institutions. Again, i'm sure pope will go too and i hope it ( i want the vatican archives, that is said contains all the most important secrets about humanity extending in underground caves for kilometres ), but i can tell you 99% first, they will have to take out Conte and creepy swamp ( 99% of our politics ).

There would be another "place of power (for the evil side)" i'd keep an eye on sometimes in Rome, l' obelisco di Ramses II (Ramses II obelisk)
