A CFZ is what the bad guys and crazy people want to target. The options are as follows: Don't ever go into a CFZ "which is impossible in some cases", go to the CFZ and don't carry a weapon, or go to a CFZ and carry a weapon. There are potential and obvious repercussions for any of these choices, and I "believe" that only on duty law enforcement can carry in those zones as well. The repercussions are felonies, jail time, loss of license, mass shootings, murders, injuries and utter chaos. Doing the right thing and the lawful thing isn't always the right decision, but once again, there are repercussions.
