I always take gun speculation and advice about what would happen with guns, from people who don’t own any, don’t know the first thing about using them, and actually believe that disarming law abiding people will stop anyone with the intent to do bad thing to others, is the right solution.
The cinema in question disarms its patrons. This is what happens when law abiding people have nothing. Criminals and thugs and unstable drug users intent on hurting others will use whatever weapons they can get.
What it all boils down to is this:
Liberals believe that our fellow humans are good, and if laws are in place, they will be followed and all will be well.
Conservatives believe that evil exists, laws don’t stop evil, and people should assume personal responsibility in protecting themselves and their families.
