Okay, so they post a sign. If you’re concealed how would they know, and on the other hand, someone wanting to shoot up the place a sign wouldn’t stop them. Just saying.
Virtually all of the CCP holders are law abiding citizens. They aren't willing to go to jail and/or lose their permit by violating the law. Most churches in Texas don't post - only the confirmed loony left.

No, all the criminals obey the law. That's why there wasn't any gun violence in Washington, DC, or Dee-troit, or Chicago...
