Why are frangible projectiles such a big deal? Safety. You miss your intended target and you risk the danger of ricochet. CTX frangible projectiles takes the danger of ricochet out of the equation. Because they break apart on impact, there's one less variable to worry about.
In home defense, eliminating the ricochet factor can mean no further damage to property or even family members.
In law enforcement it means collateral damage is diminished.
In military applications it means that when it counts, blow back and ricochet in hot spots are reduced, limiting loss of personnel.
