By modern standards orders like the Templars or the Teutonic Knights would essentially be considered Armed Security Guards (With the difference being that they were Monastic Guards/Knights when it came to the Templars) who's job is to protect missionaries, pilgrims as well as churches/relics from persecutors (And especially from terrorists, jihadists or suicide bombers).
So why don't we create Catholic based both Armed and Unarmed Security groups dedicated to doing this once again? Overseas where terrorists kill Christians or attack them as well as domestic accordingly to what is allowed.
Whether its paid or unpaid, if unpaid we can muster faithful or parish members who have experience (Or want to get some) that are willing to volunteer as well depending.
Do you know anybody capable or willing to found such a group or any of them? My parish apparently got forced out of holding rallies in the park and stopped because some anti-Catholics threw objects at them. Imagine if we had some guards like in the olden days.
All you have to do is have a master license and register a security group or company that provides 'services' to Catholics/Christians in your country/around the world depending.
