Yes... and no.
I have been morning for my brothers and sisters in Christ around who have died because someone decided to murder them since the 70's
A good 99% of the time they were totally defenseless because they were disarmed.
There is a reason that this kind of thing happens more where law abiding peaceful people are disarmed and less where they are armed.
Sometimes it is the government, sometimes it is mohammedans, sometimes it is communists, sometimes it is drug lords, sometimes it is people who hate Christianity for some reason, sometimes it is someone with a personal grudge.
All of them are given a pause when they know you are likely to be armed.
So unless you want this to happen here on a wider scale you should carry and be sure to keep your right to carry.
Because it can happen.
Let us all remember these holy martyrs in our prayers tonight.
